I have several recurves( td)50-54#@28 and shoot every day. Recently purchased a 1 piece recurve med grip just like the rest 53@28. If I shoot this bow several days in a row I get shoulder pain. None of my other bow cause pain. I installed a quiver thinking it was because it was so light and even tried heaver arrows still the same. What else should I try? As I really like the bow, shoot it well and want to keep it.
I would set it aside for a month then try it again.
And if it causes pain, I would get rid of it like the plague as I would suspect the pain will be present quickly thereafter when shooting your other bows. And once you have pain, it is a pain to get rid of. :-)
There isn't any one bow worth chronic pain which will ruin all your shooting fun. IMHO.
