I have also had problems with my sholder(sp). I am right handed and it was my left arm. I was shooting 300-400 arrows a week and it was wearing on me. My bow was set at 70lbs and I turned it down to 63#. Now, I am a pretty large guy at 6' and 275 pounds and drawing the weight was no problem, but is was wearing on me gradually.[

] The guys in my bow club warned me that I did not need to shoot that much weight, but I am hard headed and kept it up. One of the other things that hurt me I think was the weight of the bow along with a 2' stab. and a long and heavy toxonics naildriver sight. ALL OR THOSE things matter.
I am not the only one in our club that has shoulder problems. On of the guys is a long time nationally ranked shooter and has the same type of problems. IMHO drop you bow weight and enjoy shootin. If it hurts it is not fun anymore and that is what we all shoot for isnt it?
