As for the scent on flies thing. I wouldn't do it, not because of ethics, I just don't like my hands and all my gear smelling like shit, plus, I don't have much problem catching fish w/out it, so why bother? I could see scent helping out a lot in low vis situations, call me a fool, but I'm not convinced it makes much difference under normal conditions. I've outfished bait slingers on the same stretch of river. I don't care how people fish, just keep it legal, call it whatever you want, fly fishing, gear fishing, bait fishing, whatever, it's all fishing. The folks who argue about it probably get out and fish like twice a year and have nothing better to do but think about ethics all day.
