RE: Shoulder pain..
Been there, done that. I knew better too, because of all the spine problems I've got, but it's hard to put a bow down when you're having a good time with it. Wound up hurting myself so bad that I can't even get a 40 pounder to full draw anymore. Had to go compound, but at least I can pull 55 pounds on a round wheel bow.
Wish it was 20 years ago when I was shooting longbows up around 100-120 pounds. Knowing what I know now, I would've never shot over 60.
