I just bought the racquet and like it a lot. Unfortunately my elbow gets worse evry time I play with it. It's strung with Gosen Super Micro 17 at 60 lbs. Should I try ematrix 17 at 55 lbs before giving up? Or am I hurting from the high SW? My other racquets are POG OS and Babolat Pure Storm MP and my arm is fine adter playing with either of them. Thanks in advance for your advice.
