Maybe you could check out the Draw Lock, it mounts to any bow and holds it at full draw until you are ready to shoot, it even has a safety. I think they are a little over a hundred bucks. At least you could still shoot your favorite bow that you are comfortable with, it just gives you the ability to draw it with both hands, cause you hold the bow with your feet to draw it. Ive never used one but a guy that lives close to me has one because he has a bad shoulder and didnt like crossbows. He says he shoots better now than before because it always holds and releases the string the same with every shot, no creep, and no worry about anchor point. He loves it.
