I have a racquet I want to play with but it doesn't have a butt cap. Since, the racquet shop is in the other side of the city and I don't want to do a trip there, I just thought, I'd put a replacement grip on it and wrap the overgrip 2-3 times on the bottom and then do the whole thing and then string it ? Has anyone tried it ? ANd, what are the other importances of the butt cap ? Thanks.
