Thing of it is, I have also come to believe that familiarity breeds contempt, at least in the context of trout and the dry flies they see every day. I remember a couple summers ago during the green drake hatch, all my buddies were turned onto this specific V-winged pattern that rode a little lower and flatter on the surface. I tried it, and yes, it worked great. But after a few days on my favorite river, the trout wouldn't eat it anymore. The drakes were still hatching, but I think those trout, even with pea-sized brains, were able to register the fake after all of us bandwagon anglers had show the same bug to them over and over again.
