hmm I havn't tried K gut... will check it out soon... but multis are expensive stuff during the testing period..
I can certainly appreciate that, and cost should be a serious consideration. Many people feel that K Gut and K Gut Pro are overpriced, even though many also feel they play great.
Bottom line: Those who prefer Babolat Xcel or Gamma Professional, instead of Wilson NXT Tour –no need to try K Gut or K Gut Pro. But for those who really like NXT Tour – you might love K Gut and K Gut Pro – especially at mid/low tension.
To give you a bit more perspective, since you mentioned Xcel in a post above, I also played with it, as well as Gamma Professional. Both Xcel and Gamma Professional had good ball cupping (pocketing), in imitation of natural gut. But where natural gut is responsively crisp, Xcel and Gamma Professional were softer and more diffused, making it hard to tell exactly where the ball landed on the stringbed.
For me, K Gut and especially K Gut Pro have a lot more of natural gut’s crisp response along with ball cupping (pocketing), with spin, touch, feel and absolute control – while still being arm-friendly – especially at mid/low tension, which is rather protective against TE.
