I string for one Big 10 player, and one top junior. This summer, I used K-Gut for the first time. Both players absolutely love it. At first I was using a tolad string bed of K-Gut. I have since gone to using K-Gut on the Mains, and crossing with Sensation. I string both players frames at 59, and maintain the same tension of both strings. It feels great, holds tension, and neither has broken a string in a month. One of them uses extremely heavy topspin. There is minor movement. I player uses a Head Radical MP, (Youtek), the other an Extreme.
Give it a try. Yes, K-Gut is expensive, but you can get Sensation for a reasonable price. Prior the Radical player had been using Big Banger Rough, and NXT, used it for two years. The other used Pro Hurricane and X-Cell.
