I have had bucks bust me while letting down though. I draw and then they always seem to stop in the wrong spot and stay there for 5 minutes. I hold as long as I can and then have to let down. That really sucks.
Yes, that's another major concern of mine. I wish I had known when I started gearing up what I know now. I'd have gotten a 60# bow instead of a 70#. I don't have any trouble drawing it, even slowly, but I don't think I could hold at full draw for 5 minutes and still make a good shot.
