Long time pro staff user, switched about a year and a half ago to the blade 93 2013. Seemed to be everything I was missing in my game, so low powered and gave such accuracy. Than about a year in I stumbled on some PC600s at a good price. They were like the blades on fuel... Best 18x20 I can imagine playing. Hit forehands so hard and accurate. But eventually My PS85 creeped its way back in... now can't play without it. 18x20s I find limited now. Spin access is there but it is not as great. Better spin with the Blade 93.
I typically I find these racquets not as 'even' as the Pro Staffs. Every shot feels predictable with the PS, but the Blade and PC I feel the need for slight adjustments when switching shots. Maybe too used to the PS line with 16x19 / 16x18?
