Any suggestions of rackets that offer the following; 1. Power on serve 2. Plently of topspin(although not too much as i naturally hit alot of topspin anyway) 3. Between 315-325g 4. Suits a baseliner with a "run-about" game of scrambling for every ball to work a winner 5. I don't particuarly want to add lead tape 6. I generally use a tension of around 56lbs Thanks for any help.
