Copoly Hybrids – How to Choose a Cross String

This entry was posted in Ask Us, Stringing and tagged , by GGTennis. Bookmark the permalink.

Each week we receive questions from customers seeking advice about hybrid string setups, specifically with poly-based strings. This post seeks to provide a general guide to those who are considering a poly-based hybrid.

Generally the first decision to make is whether to use the poly-based strings as the main or the cross. The answer to this will depend on what the player is seeking to accomplish. If s/he is seeking greater durability, in most cases the mains will be the poly-based string with a synthetic gut cross string. (This can vary according to hitting style, but the majority of players we serve break the mains before the crosses.) If the player is seeking to add additional control to an existing synthetic gut or natural gut setup, then the poly-based string is sometimes used as a cross string.

Many who approach us already know where they want to use the poly-based string. The more important question to them, is what to use as a complimentary string? One advantage of using a hybrid over a full poly based string setup is a softer partner in the stringbed can result in greater comfort. Because the goal is often adding increased comfort, the thought is to use an ultra-comfortable multifilament string. The question is which one is most durable?

We believe the concept of using a multifilament string in hybrid with a poly-based string is flawed thinking. There are two primary reasons behind this belief.

1. Multifilament strings do not hold up well at all in a hybrid with a poly-based string. Either as a main or a cross, the poly-based string, being infinitely stiffer, will act like a saw, cutting through the multifilament in a relatively short period of time.

2. The playing characteristics of the poly-based string will dominate the stringbed. The poly-based strings possess very distinct playing properties and while they can be softened with a synthetic stringbed partner, they will still dominate the stringbed.

Because the poly-based string is dominant, we believe it is extremely difficult for even advanced recreational and league players to be able to distinguish a difference between a hybrid consisting of a soft solid core synthetic gut or a multifilament string. (NOTE: We do believe a hybrid does offer a more comfortable and different playing stringbed than a full poly-based setup.)

Since a stringbed consisting of a soft solid core synthetic gut and poly-based string will play nearly identical to a hybrid of a multifilament and poly-based, we believe the soft solid core synthetic is definitely the way to go. There are two key advantages:

A. The softer synthetic gut string will last longer.
B. The softer synthetic gut will cost less!

We are currently playtesting a variety of hybrid setups and will post results when there is enough data to be of interest. In the interim we will list some of the soft solid core synthetics that we recommend.

    I have tried a few different combinations of hybrid set-ups and I can tell a difference in a synthetic gut main and a multifilament set up. I find that with using the softer string ( either syn. gut or multi) in the mains and a copoly in the crosses, offers much more touch and control than the opposite. As stated above, the durability suffers as I go through a stringing in roughly 6-8 sets if I do not use string savers. I have sold some of my teammates on this set-up, but now they hate me because they spend more money on strings. Good luck.

    Absolutely correct! The blog entry is flawed in that the comments about multis and soft solid core strings apply more to a setup of copoly mains with a hybrid cross. This is not clear in the entry and your post helps bring a valuable alternative point of view. Thanks for sharing!

    In one of your blogs, you mentioned Weiss Cannon Super Cable as a solid core multifilament with good durability. Would it work in a poly hybrid?

    I have not had poly’s “saw” into my fairly soft cross string (NRG2), but it is true that the crosses will break before the mains. However, while poly’s can generally go a long time without breaking, they will start to deaden after just a couple of outings.

    Could you recommend three synthetic guts that would serve as a cross with a copoly main?
