Recently, I bought a nearly brand new Yonex demo racquet at a nicely discounted price. The only problem is the 4 3/8 grip size. A little too big for me and I would be much more comfortable if it were a 4 1/4. It has a molded handle so it can probably be shaved to the smaller size. I tried putting on an ultra thin over grip over the stock grip but the racquet still feels bulky. I'd try shaving it down myself but messing up could ruin the racquet. Has anyone had this done by an expert?
