I've got a fairly tender elbow and my first few experiments with poly ended with serious ache. But now i know the secret which is to go 53 lbs or lower and go with one of the new, softer co-polys. BAM is working very well for me. Go low on the tension! I started out stringing in my normal range of 56-60 and it hurt. As soon as i dropped to 52-53, no ache or pain whatsoever. Poly can handle lower tensions and maintain control, don't be afraid to go low. 51 yr old 4.5 here, also had arthroscopic rotator cuff surgery 4 years ago, so i don't take chances with risky setups. Stay away from Lux BB, go with soft co-polys/low tension.
