So I've played with all the tour 90s, my favorite being the k90 and the Prostaff tour 90 2003. I think wilson would get it perfect if they took the k90 racquet shape, design weight and balance, and made it out of the same material as the Prostaff tour 90 2003, or the Wilson Prostaff 85. No gimmicks, no new materials, no bells and whistles, and with good quality control. Just sayin'. Hay Wilson. . . .hint, hint. . .
