4g: what makes it difernt to other polys?
I played with a Yonex 97 tour 330 with 4g and it felt very good. Will try this string in the 97 Tour 310 version.
4g has very good control, retains tension well and has a particular feel. So, what makes it different from other polys, if that is the case?
Why do many people say it is not designed for spin hitters?
Thanks for the reply.

Each string has a unique blend of specs which separate it from other strings. Included in those specs are stiffness, which greatly affects how it feels and plays; spin potential, which is partially affected by a string's capacity to move out of position and snapback; and a particular rate of tension loss, which affects how it feels and plays over time. In addition to these things, which we've measured in the lab, there are things like power, which turns out to be quite complicated once you get into the physics. Having edited playtests for almost 10 years years (at the USRSA and now at TW) I am well beyond amazed at how much disagreement there is over things like spin, power, comfort, playability, touch and optimal tension.
In our lab 4G had great tension maintenance (for a poly), though we only measure short term tension loss. We have not done a study of how well 4G holds tension over the long haul. On the anecdotal front, our playtesters loved 4G, including Chris Edwards who has an extremely sophisticated poly palette. I can't speak to what others have said about its spin potential. Perhaps they are reacting to the fact that it isn't shaped and doesn't grip the ball as well - the upshot of which is that they cannot attack the ball as aggressively (both in terms of racquet speed & angle). But it's very hard to comment on what is inside the minds of others.
I tend to think that over 95% of, say, spin and power comes from the stroke. (The racquet and tension also play a role.) I also think that power is often confused with a stringbed's trajectory response. For these reasons I tend to default to the player's on-court experience. This translates into a frustratingly simple answer to your question: your perception of what works best for you is what separates a string.
I encourage you to check out the string tool in TWU. This will give you a snapshot of 4G's specs, and it might serve as a nice counterweight to the anecdotal stuff you've heard. If you need help using it, email me at firstname.lastname@example.org. Subject: Question for Jonathan
