Have been playing with the X-Force Pro for about a year, and in general I really like the frame. I have found my self leading it up a bit lately in the search for more power, but it has seemed to only increase the muted feel the racquet already has. I love the flex of the frame, very comfortable, and I love the spin potential, but I dislike the power level (I string it low 50's with full co-poly) and lack of feel. So... my question is two-fold: should I experiment with a hybrid of say natty gut mains and poly crosses to increase power levels and feel, or should I look elsewhere for a new frame? Any suggestions on strings and/or frames is appreciated. Thanks.
