Per the doctor's recent orders, I am now relegated to only playing doubles (chronic knee issues. Five surgeries and I'm only 35.) Although I will miss playing singles, I love doubles so I'm not completely devastated. As a racquetholic, I figured this might be a perfect time to "test" more doubles' appropriate frames. (If there was ever a time I could justify buying new frames to my wife, this is it.) About me: 4.5 Doubles player. For a shorter guy, I have a big first serve and competent kick second serve. Semi-western to full western forehand. One-handed backhand. Volleys are my strength. Current frame specs - 12.3 strung weight. 4HL. 90 square inch head. 14x18 string pattern. Things that are most important to me: 1. Maintaining pace on serve; 2. Solid volleys but can still maintain feel; 3. At least 3HL. Otherwise, I cannot pronate properly on my serve. 4. Maneuverable enough that I can "get over" my one-handed backhand. Any suggestions?
