I'm closer to 60 than 50 and am going to have to pace myself to stay in this game for another ten years. Went to a 60 lb. bow. Like the smoother drawing bows that are of moderate speed. Rotator cuff and elbow get real tender if I shoot for an extended session. Takes a least a week to recover. But I can still easily shoot enough to get the bow tuned and sighted in. 3-D is pretty much out of the question, though.
