Well I have tried all sorts of polys in it from solinco to weiscannon to Gamma Zo Tour Rough and so far have stuck to Tourna BHBR 17G. And love the Zo tour. Ordered 10 new sets of different polys to try with my new racquet so lets see how it goes.
But yes I noticed great for FHS but my backhand suffered in regards to depth . HAd to adjust big time but still feel I have to be in great position to hit BHS with this. But I must say great stick surprising not many people on TW play with this or Donnay.
