If the purpose of a particular tournament is to limit the equipment to hunting bows and arrows, then the only reasonable rule would be whatever is legal to hunt with in that particular state. Setting arbitrary limits on arrow weight is not going to have any effect on a 30 year-old man shooting a 60# bow, but could stack the deck against a 75 year-old man or a 14 year-old girl who are shooting 35# bows because that's all they can handle. Is that a good result? So you say, no! no! We just don't want some hotshot coming in and winning the tournament shooting knitting needles out of a 40# bow. Well, people have a choice of what they bring to a tournament. As expressed here, most people who choose to shoot hunting equipment at tournaments have made a conscious decision that preparing for hunting is more important than winning the tournament. If some modern day Howard Hill can do both, then I'm sure he will get all the extra recognition he deserves. But for someone to make a choice to compete with less than optimal equipment, and then to complain because someone else won, just sounds silly to me.
