I worked my way up to a 74 lb. recurve in my younger days and shot it pretty well. Then one day I heard a tearing sound in my shoulder. It didn’t hurt but it was an unnerving sound. I continued to shoot the heavy bow for a number of years but not as well. Now, in my older years, I struggle with a 55 lb. bow and I’m not having as much fun. My shoulder aches every time it gets damp in the spring or fall. It ain’t worth the anguish and early end to a bow shootin’ career to shoot the heavy bow. I agree with Steve on the injury issue.
