JET Method – Your Online Guide to How and Why?

This entry was posted in L-TEC Strings, Stringing and tagged by GGTennis. Bookmark the permalink.

Many of our blog followers are likely aware that Tennis Warehouse has picked up L-TEC Premium strings to make available to internet customers.  The purpose of today’s blog entry is to give those who are purchasing L-TEC strings online the means to string them so that they can achieve the best possible results.  Toward this end we are proud to present the JET Method of stringing for constant pull stringing machines using fixed clamps.


The JET Method of stringing combined with L-TEC Premium strings provide players with an equipment advantage delivering the best possible on-court results.
There are 3 major components of the method that should be implemented in unison to achieve optimal results.

  1.  Analyzing and calculating the player’s ideal string bed tension.
  2.  Choosing the best L-TEC string(s) to improve the player’s game.
  3.  Applying the exact set tensions and the JET Method of stringing to achieve the precise overall string-bed tension required by the player.

There is a very precise methodology and tools that allow the stringer to string at lower tensions. The stringing technique/method preserves the elasticity of the string and ultimately allows the string bed to hold the desirable playing properties for an extended period of time.


Twenty-four hours after stringing a racquet the overall stringbed tension will measure at least 4 – 6 pounds lower than the tension that was originally set on the machine. (Often more)  After 1 hour of play there will be a further loss of tension of at least 2 pounds.

The JET Method of stringing progressively increases the overall string-bed tension to at least 3 pounds higher (for a 16*19 string pattern) than the SET Tension on the machine and up to 5 pounds higher (for a 18*20 string-pattern).

Therefore, to obtain a similar overall string-bed tension when using the JET Method, the Reference SET tension should be reduced from 7 to 10 pounds depending on the machine and the string-pattern. The Reference SET Tension on the machine is much lower, but the feeling of stiffness in the string-bed will be quite comparable. The vastly improved comfort, power, control and spin, as well as the capacity to hold tension and maintain an initial playability for much longer than usual stringing methods are the most evident advantages of the JET Method of stringing.


If necessary, carefully use an awl to enlarge the grommet holes on #6 main (16 main pattern) or #7 main (18 main pattern) for tie-off. (This will be either top or bottom depending on where main strings end.)

Enlarge the grommet hole on the third cross from bottom of the frame for tie-off. (Depending on pattern, this can sometimes vary. The objective is to tie-off as close to the 2nd to last cross as possible).


  1. String first four center mains on each side at reference tension.
  2. Next 2 (on 16 mains) or 3 (on 18 mains) reduce tension by 4 pounds.
  3. On a 16 main pattern after pulling main #6 skip over to #8. Increase tension 4 pounds (to reference tension) before tensioning.  (#8 will be pulled at reference tension).  On an 18 main pattern after pulling #7 skip over to #9. Increase tension 4 pounds before tensioning.
  4. Fill-in main #7 (on a 16 main or #8 on an 18 main) which will be the last main. Adjust tension by adding an additional 4 pounds (reference plus 4.)
  5. Tie off on main #6 (16 main) or #7 (18 main).


  1. IMPORTANT:  Each cross string must be held under tension at least 20 seconds before clamping off.  We recommend weaving the next cross while the previous one remains under tension.
  2. Start first three cross strings and tension at same tension as final mains. (+4 over reference tension)
  3. After installing 3rd cross string, reduce tension 6 pounds and install the rest of the cross strings   (This will be reference – 2)
  4. After stringing 3rd last cross, loop over and weave final cross. Increase tension +6 pounds.
  5. For last cross string fill in second from bottom.  Tie off on 3rd from bottom.

 Always give professional finish by straightening strings using The String Thing!

Some points to keep in mind :

1.    This presentation of the JET Method is intended for stringers using an electronic constant pull stringing machine with fixed clamps.
2.    In the quest for stringing perfection, this is not the ideal stringing machine. However, by using the JET Method conscientiously the results can be remarkably good.
3.    If you have the choice of pulling speeds, always select the slowest.
4.    Wait 5 seconds before clamping off each main and a minimum of 20 seconds before clamping each of the crosses. (weave in the following cross while the previous cross is being tensioned, this can save a lot of time).
5.    To become a competent stringer capable of giving top quality string-jobs when applying the JET Method requires many hours to learn and to practice this craft. It is necessary to control the results obtained string by string with a Stringmeter to understand where you are losing tension and where you need to improve your techniques to overcome these weaknesses in your way of working.
6.    To aim for the end results on the court for your player requires strong motivation and real passion for your profession. Without this your will to improve as a stringer and the capacity to put into question your habits in the way you have been stringing for years, you will not be able to acquire the efficiency in this craft necessary to obtain JET Method Certification. You may well improve your results for your players and that would be a very good start, it may even encourage you to continue to learn to become a much better stringer, even a craftsman. Now it’s up to you!


Stringway ML 100 or ML 120: Constant pull drop weight machine. Best for extended pulls on cross strings which allows crosses to be installed at lower tensions resulting in maximum preservation of elasticity and harmonizing of string-bed.

Stringway Flying-clamps: 2 x Triple-clamps and 1 x Double-clamp.
Eliminates the effects of the drawback (often a problem with fixed clamps), it also reduces the risk of string slippage (a cause of loss of tension and damage to strings).

 String-A-Lyzer: This tool is still in the manufacturing process and will be essential for mastering the process and measuring results.  Available in March 2012.

 Stringway Cross Stringing Tools: These tools allow cross strings to be installed with a minimum of friction and twisting.  Especially important with profiled strings.

    So, if one wants a feel of 52 pounds, he/she should set his/her reference tension at 42 to 45 pounds? And if one is stringing gut/poly hybrid, should he/she use JET for the mains as well? Thanks!

  2. Sir.N on said:

    The Ref-2 lbs for crosses, is this the starting point as considered for a setup with the same string in mains and crosses? If thinner crosses are used (or strings with other shapes and therefore other cross-section area), how should this be accounted for, if at all?

  3. GGTennis on said:

    Sir N – Thank you for your interest in the JET Method. Your question is excellent. In some instances, depending on gauge/shape/composition variables, the tension in the crosses may indeed benefit from being tweaked. When using this method with L-TEC Premium strings the formula is stable and works with all strings in the line.

  4. Florin on said:

    Hi. Interesting article but I must say that I’m a bit confused. I’ve learned JE method more than a year ago, but there are some changes in the method described in your post versus what initially John has stated in his two pdf files.
    it was like:
    L1+L2+L3/R1+R2+R3 – ref tension – RT1
    L4+L5+L6/R4+R5+R6 (16 x 19) – RT1 less 2 kg (4 pounds) – RT2
    for L7,L8,R7,R8 – double pull with RT2 plus 4kg (8 pounds) where L7/R7 skipped, loop to L8/R* (not stringing) and than L7/R7 with double pull.
    Start C2, C1, – double pull at RT2
    C3 to C17 (16 x 19) – RT2 less 2kg = RT1
    C18, C19 – RT1 plus 4 kg.

    I have applied this method every time since then, with excellent results.
    So, this is a new method?
    Thank you

  5. GGTennis on said:

    Florin –

    Yes. Mr. Elliot has revised his process. He continues to refine and improve upon the method. I have no doubt you are getting excellent results with the older method. You are welcome to continue using it or you can try the revised method to see if you find that it performs even better. Best of luck to you!

    • Florin on said:

      I’ll trial the new one for sure. If it’s at least as best as the old one than it should be just fine.
      I’m a proud owner of a Stringway ML120 and I’m also using the Tension selector. According to this tool, different tensions for Mains and Crosses are provided and so for various racquets the difference in tension between mains and crosses varies from 2 pounds (1kg) to 4 pounds or even -2 pounds. Having checked my stringjobs, there were no frames distortions and I’m wondering if the JET method (old or new) would create the same results no matter what the racquet variant is (taking in consideration that the method is applying 1 kg/2 pounds difference between mains and crosses (at least the majority of the strings). What is your opinion? Thank you

  6. GGTennis on said:

    I do not use the Tension selector. From what I understand of it and the construction of strings, I think it is best applied with synthetic gut strings. I am no expert and that is purely my personal hunch…nothing more.

    In terms of the JET Method, you will be extending the pulling time on the crosses. This has the effect of raising the tension in the entire string bed. There is no reason/need to adjust the tensions beyond what the method suggests. The majority of the crosses are strung at reference – 2, but the extended pulling time effectively raises the overall tension while preserving 100% of the elasticity of the strings.

  7. Florin on said:

    🙂 I’ve just read the previous posts regarding JET method (the old one) and it’s only one month ago. Things are moving so fast in the internet era!
    Anyhow, all the best to you for sharing all these nice and useful info and I must say that I really appreciate Mr. Eliot’s work.

      I believe that is the reason for the slight differences.

  8. JB on said:


    Could you please comment on the suggestion to use 2 triple clamps and 1 double clamp; at what points in the process are each used? I have a LaserFibre branded ML90 with the double action T98 fixed clamps and drawback has always been a bit of a problem. I’m looking for a better way and wondering if the investment in the flying clamps is worthwhile. Thanks.

  9. GGTennis on said:

    You can certainly do a very fine job with one double and 1 triple, but having 2 triples is easier and offers some options for those who are extremely obsessive.

    For me, when getting started I use 1 double and 1 triple until the center 3 mains are tensioned. At that point there is room to use 2 triples. I prefer the triples because the twisting is greatly reduced. Also they are spectacularly solid when clamping off the outer mains for the tie-off.

    For the crosses, I sometimes will begin with the triple because you can use the two outer channels for racquets where the spacing is wider and the head and throat. I am still testing results with using 2 triples vs one triple for clamping the crosses. Most of the time I use two. I find them to be especially useful when clamping off the last cross. I use both of them to fend off any twisting. I have no reservations about strongly recommending Stringway flying clamps for any stringer who is seeking the best possible results from a clamping system. Hope this helps.

    Hi guys,

    I would like to apply the JET (or even older Jaycee method) to my machine. I do not own a Stringway machine or any other of their products. I would not be adverse to owning one of these machines, however, I have a lock-out style machine that I can use very well. I am usually very close to reference tension when the string job is completed (actual tension usually doesn’t vary by more than 2 lbs. from reference). I am intrigued by the John Elliot methods. What recommendations would you have for me to adapt this method to my machine? I would be open to either Elliot method. Presently, I use Babolat VS Team in the mains and Volkl Gripper in the crosses on my Donnay Formula 100 (16×19). This is a stiff racquet with a balance point of 4pts HL. I have been stringing with a modified proportional set-up using reference 57# for Mains and 55# for crosses. I tension the first 8 mains at reference. Then 4,5 & 6 mains each drop 2# to 55#, 53# & 51#, respectively. I then raise tension 10-12% for mains 7 & 8 pulled together. The top 3 crosses begin at 6# below reference and increase sequentially up to reference by the 4th cross(x1=49;x2=51;x3=53;x4-16=55). I continue the rest of the crosses at reference until I reach the last 3 crosses. Then I drop 2 lbs below reference for each of them (17,18,& 19 each at 53#). This seems to give me a nice sweet spot and a little more comfort on off shots. I also fine that using this string set-up holds tension pretty and is very accurate. Ive dropped only 4 DT in 2+ months with approximately 56-60 hours of play. These racquets are playing very well at DT = 34. I don’t usually play with polys because they are too hard on my arm.
    However, after reading your blogs on the Jaycee method that allows for much lower tensions using polys, I would be interested in testing this out for myself. I would appreciate suggestions for my present string combo (natural gut/multi)and recommendations for a poly in terms of which method (JET or Jaycee old) would be good and what reference tensions to use. I eagerly await your insights and recommendations. I am always open to new ideas and methods. I also look forward to all of your posts.



  11. GGTennis on said:

    Bobbyj – Thanks for visiting our site. With your equipment I would suggest following the JET Method with an added caveat. When pulling tension on the crosses pull very slowly until the machine locks. At that point string the next cross string without releasing tension. Now go back and re-pull, taking up any slack. Now clamp off and repeat for all crosses.

    I do not have any recommendations for a gut/multi hybrid. That combination is outside of my specialty area. It sounds to me like what you are doing with it is working for you. I would keep to the program there.

    In regards to full poly, L-TEC strings are specifically designed to go hand-in-hand with the JET Method. You could go with a poly/syn combination using the L-TEC Premium 4S for mains with L-TEC Premium Gut for crosses. In my Formula 100 demo I currently have a full poly hybrid. L-TEC Premium OS 17 Neon mains with L-TEC Premium 4S crosses strung at 46 lbs reference. It is getting good reviews and remains fairly comfortable. The DT is currently 28 and it is playing well at that reading.

    • Kf on said:

      From the ERT 300 guide, a dynamic tension reading of 28 or lower is strongly not recommended… They actually say to restring when getting to 28.

      But with your full poly setup with this method, do you actually recommend 28 dt as a reasonable and playable base starting number?

  12. bobbyj on said:

    Hi guys,

    This site so neat. Thanks for the information. I will try your suggestions and report back. I did try the older jaycee method on an old volkl classic v1 using Gamma ZO Verve with really low tension ( 50# reference; DT = 33, finished tension 48#). Not too bad, but I think that I lost some tension in the process. I like the idea of pulling tension slowly (at about a 6-8 second rate) for each string, then running the next cross, retensioning the one before it, then clamping. This may bring the finished tension closer to the reference tension with a little tighter stringbed. I must say, I had a lot more zip off the stringbed at the lower tension using this method with this Poly than I used to get at higher tensions. I experienced a lot more comfort as well. I do like the natty gut/multi combo the best an will continue with that set-up; however, I will try this set-up using the JET method with your suggested tensioning at a somewhat higher reference tension than I used with the Polys. I will also report back on this. I must say, the system I’m using now works quite well but I won’t know what the better system is for me until I try both. Talk to you soon. Also, how can i order the suggested L-TEC strings?

    Hi guys,

    I have another question regarding the JET method just to make sure I understand the process and I’m on the right track. When just the mains are completed (crosses not in yet),what should the tonal sound be for all the mains at that point ideally? I’m not referring to the actual pitch of each string because that would be based on the tension I chose. However, should R1 and L1 be at the same tone, then R2 and L2 be equal in tone but just a little higher than R1 and L1, then R3 and L3 at the same tone but a little higher, etc.? So then as you strum the finished mains from one side to the other, should the tonal sound go proportionately from high to low (in the center) then back to high again (graphically, it should resemble a ‘V’ shape)? I hope that this is easy enough to understand and that I didn’t confuse you too much. Thanks for your response in advance.



  15. GGTennis on said:

    bobbyj – Let’s not get too complicated here. I suppose that ideally what you are shooting for makes perfect sense. However, once you start tuning looking for precise tonal perfection, you are adding much more work than needed. What is important is that tones from the center strings to the outer strings gradually raise in pitch. At the end of the string job you can measure the strings with a Stringmeter. If you are doing the method properly each of the mains will give you the same tension reading. It takes a while to get to this point and you can measure, learn and adjust. However, the only time you really need to do serious tuning with the JET Method is on the outer two mains.

    • bobbyj on said:

      Hi guys,

      Thank you as always for your responses. When you responded to my question on April 1st, you mentioned that tonal perfection (matching the tones equally on both sides as they progressed outward) wasn’t exactly the aim of the JET method as long as the tones increased sequentially from the center to the outer frame(if I understood you correctly). You also mentioned the the only time I would need to do some serious tuning was for the outer two mains. Could you explain that comment further? Up to this point, I was trying to match each sequential main on either side with equal tones and that proved to be quite frustrating. I did accomplish that a couple of times, but it was inconsistent and damned frustrating in the process.


  16. bobbyj on said:

    Thanks for your early response, guys. That’s clearer. I have achieved a tonal balance on both sides of center as I progressed to the outer mains on one job using Zyex mains. Then I couldn’t achieve that on another job. That second time, I was using a natural gut in the mains. When I did achieve the tonal balance on the mains, the finished string job showed similar tension on all the mains. The finished string job for the second attempt using natural gut mains wasn’t as balanced. Some stings raised in tonal sound and others stayed the same as I progressed from the center to the outer string bed. I’m not sure if it’s the string, the clamps, or the stringer…or may be all of the above. Ultimately, I will continue to persevere. Should the same technique end in similar results no matter what string you are using? Also, with natural gut mains and multifiliment crosses, would it make sense to go a little higher on reference tension given the power and elasticity of natural gut? I appreciate and look forward to you response.

  18. GGTennis on said:

    The final two mains involve overtensioning the outer main while under tension so that after tying off main #7 (assuming 16 mains) you can borrow the extra tension from number 8 and move it to number 7. Almost each week I provide a live demonstration on Tuesdays at 1;00 EST via our Google+ web site. If you would like to join us one week, you are welcome to participate.

  19. bobbyj on said:

    Thanks for the explanation. That makes sense. I wasn’t sure why the 7th main was tensioned last. I would like to tune in on your live demos. Can you tell me how I can access it? Also, just wanted to say that I’m looking forward to receiving my L-TEC strings that you suggested. I ordered them today and should be receiving them in a week or so. Thanks, again.

    Hi guys,

    I have been using the JET method with what I believe to be relative success based on what you’ve suggested to me, plus the posts outlining the JET method above. I have been using Premium 4S in the M’s and Premium gut for the X’s. Even though I use a crank machine, I think the final product isn’t too bad, especially using a method outlined in a fairly recent post by a gentleman who watched John Elliot do his method on a Prince Neos at the Symposium. The question I have for you today is my friend wants me to string his son’s Head Micro Gel (18×20)with ALU Power. I was planning to use the JET method. Any recommendations for modifications to the method outlined above that I might consider based on the string used and string pattern of the racquet? Thanks as always for your comments and suggestions.


  21. bobbyj on said:

    Thanks for your rapid reply to my post on April 29th. I am also curious as to what tensions to use when applying the JET method in a hybrid set up with lux (for instance) in the mains, and a softer multifiliment for the crosses. I think that I’ve read form earlier posts (by John Elliot) that the polys are best strung about two lbs. lower than multi’s as a rule of thumb. In the JET method, the crosses are mostly two lbs lower than reference. So if you are using the poly’s in the mains, how do you deal with the softer crosses?

  22. Tom on said:

    Hello, I too am very interesten in this method of stringing. My standard string is Signum Pro Hyperion 1,24mm and I string it at 52lbs (23,5kg) in the mains and 50 lbs (22,5kg) in the crosses, using the standard old way of stringing on a drop weight machine. The string is a round co-poly and is really soft. Now I wonder what reference tension should I choose, so that after stringing with this new method, the stringbed would feel pretty much the same.

  23. GGTennis on said:

    We have a new tool that will be introduced very soon that should take a lot of the guesswork out. It will measure the actual stringbed tension. Without diagnostics I will have to take a wild guess on where to suggest starting. Using the JET Method I would suggest a reference tension of 48lbs to approximate what you may be getting right now. Again, this is an ESTIMATE. It could be lower, but without being able to measure the stringbed you will need to start and do some trial and error. Sorry I can not be more specific for you.

    Do I have to wait 20 seconds stringing L-tec premium gut in cross and prestretch it?

  25. GGTennis on said:

    We do not prestretch any of the L-TEC strings. We do extend the pulling time of the premium gut as well as the copolys.

  26. Cole McDowell on said:

    Is the JET method more difficult to use than other methods? I am just learning to string, And have only strung one racket before. Should I do the JET method on my next racket, or should I get more practice using traditional methods first?

  27. GGTennis on said:


    The JET Method certainly has more steps, but it could be argued the best time to learn it is when you are first learning to string. The results with poly-based strings are superior to traditional methods of stringing. I believe it is well worth the extra effort.

  28. Adam on said:

    Could you please clarify the following statement:

    “…to obtain a similar overall string-bed tension when using the JET Method, the Reference SET tension should be reduced from 7 to 10 pounds depending on the machine and the string-pattern.”

    So, for example if I want to string a 16X19 frame with poly mains at 50 lbs and synthetic crosses at 46 lbs., what would be the reference set tension using this method?

    • GGTennis on said:

      It really would not be possible to achieve what you want using JET. If you wanted the poly mains to be 46 and the synthetic crosses to be around 50 you would probably use a reference tension of 44 with the JET calculator and then increase the crosses +2.

      • Adam on said:

        Ok. Why does your blog post recommend a 7-10 pound reduction in reference tension and you are only recommending a reduction of 2 pounds???

  29. GGTennis on said:

    Because your starting tension is NOT beyond the elastic limit of poly-based strings.

    • Adam on said:

      Ok. How would the reference tension change for gut mains and poly crosses?

      • GGTennis on said:

        The JET Method was originally designed for use with full poly setups. It was adjusted for poly/synthetic and/or poly/gut setups where polys are used as the main string. If you want to use a reverse setup with gut in mains then I would suggest stringing with the traditional method. However, I would encourage you to use a slow pulling speed for the poly crosses and I would install the poly crosses 4 lbs lower than the gut mains.

        • Adam on said:

          Ok. So, for a gut main and poly setup you are suggesting NOT to use the JET Method? I thought the point of this method was to help ensure a more consistent tension on each string and the overall string bed. Wouldn’t these stringing principles apply no matter what the string?

  30. GGTennis on said:

    There are a few nuances we use with the JET Method when we are dealing with situations that are not related to full-poly setups. The purpose of the JET Method is to create a stable and consistent stringbed that maintains that consistency throughout the life of the string. You are correct that the principles apply across the board, but to get into the business of trying to detail the nuances for every situation is not really the purpose of the post.

    If you came to me with a gut main/poly cross request I would help you determine where we wanted the final stingbed stiffness to fall. Let’s say we want a final stringbed stiffness of 50lbs. I would take the natural gut and string it at a reference tension of 48 using JET principles. I would then put the poly cross string in at 47 using JET principles unless using the 4S, in which case I would probably put the crosses in at 46. It should be noted that I have strung hundreds of racquets with this method and I know that with my machine, my clamps and my technique that these tensions will produce the final stringbed stiffness I am seeking.

    If I were to advise a stringer how to get very good results with a blend of gut mains and poly crosses, I would give the suggestion I provided above. It is easier to understand, manage and execute. It produces a very good result.

  31. Jeffrey on said:

    Hi GG. I just purchased some L-TEC strings (Premium 5S Sterling – Mains, Premium 3S Black – Crosses), and a Stringmeter and want to install them with my Alpha String Pal (Drop weight, flying clamps) on to my Prince EXO3 Tour 100’s (16×18). Do I use the JET method as described in this post ? It says it is for an electric CP machine. Should I use the Stringmeter to check each main after tensioning and readjust tension? After stringing each cross and waiting 20 sec. should I pull some tension if it drops? Should I use two clamps when string crosses? Any other tips or instructions would be most welcome. Thank you.

  32. Daniel on said:

    So, if I usually string my racquet at 52 pounds, is that my Reference Tension?

  33. Carl on said:

    I find this whole thing VERY confusing. First it is claimed:

    The JET Method of stringing progressively increases the overall string-bed tension to at least 3 pounds higher (for a 16*19 string pattern) than the SET Tension on the machine and up to 5 pounds higher (for a 18*20 string-pattern).

    Then the rec of 7-10 lbs is mentioned. Why not 3-5lbs based on the string pattern listed above. If its 3 lbs tighter then why not a 3lb reduction?? What am I missing?

    How do these numbers change for Kevlar mains and poly crosses?

    Finally I am stringing really low and if I go lower to follow the JET method I will be below the minimum tension of 15lbs on the machine. Last kev/poly was 17/17lbs. How would I adjust for l-tec strings?

  34. Rich on said:

    I’ve been using this method for a while now with great results. Always so far using full poly setups. I want to give a hybrid set up a try with poly mains and synthetic gut crosses. I see a similar question to this above, but I’m not sure if I understand correctly. In my typical setup up of full poly I use 42 lb. reference tension in the calculator and adjust accordingly from that number. If I use Syn Gut in the crosses what would I need to do to ensure my end result is pretty similar in overall stringed tension to what I’m used to?

  35. GGTennis on said:

    Yes lower ERT readings are normal with JET. That is one reason we no longer use ERT. We suggest using stringmeter or tension analyzer.

    the clamp cannot get close enough to the racquet edge. Is that the
    reason why I still have a lost of tension ( about 5 to 7 pounds ).

    Whould it be a good idea to clamp the fixed clamp that is still there on my pioneer dc plus and back it up with the triple flying
    clamps so there less untensionned string.

    Hi guys. I have a similar question to Michel’s but sadly it looks like this forum isn’t supported anymore.

    When finishing the crosses, just like the mains, it’s suggested to skip the 2nd to last cross and tension the very last cross, THEN the last cross to be tensioned would be the 2nd to last. The issue I’m having is the very last cross is at least an inch and a half from the 3rd to last. How are you guys clamping this? I have a String way triple clamp (and an ML 100) and it’s still way to far away.

    Our forum is still supported, but has been undergoing spam attacks. Somedays we receive 40+ posts and 39 will be spam. Sometimes when plowing through the spam to keep it from appearing to users, we miss a question and delete it in our control panel. Apparently that is what happened with Michel. Sorry.

    Hello. I just recently had my rackets restung and the string told they were using the USRSA proportional string method, which he said was the bascially the same as the Jet method.

    He told he used this tool to set the tension for each string:

    Finally he is using a babolat sensor expert machine which is calibrated as often as recommeded.

    I found however that the 4G strings I had done are much tighter overall than what I requested (50lbs in Main). Using a little tourna tension measuring tool, its coming out to 55lbs on just the 2 interior mains and then jumped to 60lbs the next couple outer strings, then progressively tighter up to almost 70lbs on the outer most strings.

    Do these measurements make sense? Is that in line with that is intended?

    Is the goal of the jet method to have higher tension on the outer strings? I thought it the purpose was to end up, after static and dynamic tension loss, to have a uniform tension across the entire bed.

    Do you have any advice?

    If using the JET method with a hybrid with poly mains and synthetic gut crosses would you change any if the relative reference tensions from above?
