I'd argue that it's not the fish's preference but the conditions under which the GL fish are sought, cold hard midwest winter verses springtime in the cascades and olympics. That and the fact that trib fishermen
like different and smaller flies, which is often of equal influence in popularization of flies.
Your thoughts on that philosophy?

Best advice I can give is to get a copy of "Steelhead Dreams" by Matt Supinski. It is writen about the Great Lakes fishery. Color plates and recipes are shown. The other books are too traditional - trib fish like different - and smaller - flies.
