Oh yeah, well I mean I was just trying to point out (to the idiot) the fact that there was tennis and Pro Staffs before Federer was ever near a camera. But yes, most people who are using Pro Staffs because of... Pro Staffs.Then there are the people, like myself, who use the 90 because of nobody. I was using the PS 6.0 95 at the time when I tried the 90. I found that the smaller head and higher swingweight gave me more stability and plow-through while improving accuracy, and still maintained all the positive attributes of the 95, such as that sweet graphite/kevlar box beam feel and control.
