I currently use Prostaff 90 2012 version with Grip L3 (4 3/8). Of all the rackets I have used, wilson has the best shaped grips. I played a bit with a prestige pro and the grip was quite thicker (though the same size according to head). Are all the wilson grips the same shape and size? I'm thinking of purchasing a 6.1 95 as they are cheap as chips now. Is the grip the same shape as the pro staff?
