I've been using Whiting, American Hackles for the last 4 years and find their grizzly capes (for splayed) and saddles to be of the very quality I need here for the big West Cost fish and flies, wide thick and webby with a strong consistant round stem.
Your comments about where the "Keys" style or Homer Rhode style tarpon flies came from is a real issue with me. Too often so called "Flyfishing Celebrities" grab fame for flies they virtually stole from someone else. And if you look at any publication today you'll see tyers doing the same thing.
And you know alot of very good tyers over the years have not published their flies just because they don't want to be have their name associated with that.
