Yep, if you can execute good shots with heavy bows, then by all means, shoot them. I haven't seen many who can, though, and a 40lb bow will shoot clean through the things most people want to shoot. Going to a trad 3D shoot is actually scary, when you consider that those people are going to be shooting at live animals. It depressed the hell out of me when I went to my first one, and I include myself in that. It took me a long, long time to realize that I can't shoot anything over 45lbs well for more than about 3 shots, and the scary thing is that most of the other shooters thought I was really good when I was shooting heavy bows.
