With the clarification given, I would agree that working with a heavier weight can be productive. Again, though, take your time, and work up slowly. Increase reps before increasing weight. My cuff was not torn, so rehabbing my shoulder was not as drawn out as some others, yet only a few arrows at the time could be shot with comfort and control. Over a period of several weeks, I worked up to shooting the heavy bows comfortably. Going slowly, you should be able to achieve your goal - just remember "no pain, no gain" is a bunch of horse puckey. It is a signal to back off a bit. Still, use common sense and discuss your idea with your doctor to be sure he knows you are going to heavier weights. A doctor's advice is always your best guide. Good luck!
