I liked k gut because it had a ton of feel and was pretty good all around in terms of spin power and control. It would break at 8-10 hrs and I was fine with that.
I like rpm and Nat gut because I can rip my forehand and the spin drops it in. I just feel like the rpm dies to fast because of how much I play. Is there anything out there similar to k gut or a poly similar to rpm that lasts longer?
