I have been fly fishing and tying flies for 50+ years now. Over that time I have tied lots of "variations" of popular flies and I never thought about putting my name on them. They are simply flies. If someone asked me what fly I am using, if it was a "standard pattern" I tell them, if it was one of my variations I show them the fly. These are flies - stuff wrapped on a hook designed to catch fish. Not to demean anyone but does it really matter who thought up the original idea, and how can we really ever know that the fly that you thought you invented really hadn't been tied for years by someone else? Unless you are using a new material that no one else has ever used to tie a fly the chances are pretty good that someone, somewhere has tied the same thing. If the only thing I'm remembered for after I cast off this mortal coil is a fly that I tied I have lived a pretty shallow life.
