For sale is my Wilson Hyper Pro-Staff 6.1 that I've used for 1 season. It's in good condition--about 8 out of 10--(8 only for cosmetic reasons, as the top has scratches and a few on the sides. The racquet is a year old. I still have the original strings on it.) Grip size is 4 1/2. Please email me for more info. shinpaul (at) hotmail (dot) com I also have excellent feedback on **** and paypal. I have this racquet on ****, but I will end the auction early for a sale. Asking $75.
