Wow, you guys are full of great stories and information! After reading all this, I went into my fly box last night and smashed down the barbs on all of my flies. I hate to think of how many fish I may have irreparably injured over the years using barbed hooks. Even if I was to never catch another fish, at least I can now fish with a more clear conscience...

And once I start tying, I'll probably just use barbless hooks. I broke the points off of a couple of my flies while smashing them down...
