Many on this board say that heavy racquets can exacerbate shoulder problems, whereas light stiff racquets can cause tennis elbow. I have had both elbow and shoulder issues, but most recently the shoulder has really been bothering me. I prefer heavy (and extended) racquets, currently playing with Babolat Pure Control Plus, because I regularly go up against heavy hitters and I need the stability. I have tried playing with string type/tension to make the Bab more arm-friendly, to no avail. I don't want to develop any long-term complications and think I better switch racquets. POG OS is supposed to be shoulder and elbow friendly, but wouldn't the relatively high SW make my shoulder worse? And if I have to go to a lighter racquet to relieve my shoulder pain, which sub-11 oz racquet offers the most stability?
