Hi everyone, I am currently demoing a 4 3/8 Wilson Tour 90 and absoultely love it, but the grip is just a little too thick for me. The ones they have on stock are actually 4 1/4 so I am thinking of buying it, but my question is, how much different will the racquet feel? Is the weight different according to grip size? What about balance? I know that Yonex racquets (at least the old models that I have) differ in weight depending on grip size, but what about Wilson? Anybody know? Any help will be appreciated!!
