The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
Like Spence, I like Matthews' technique. It really stands the wing up and keeps it there. I typically only throw one wrap in between each bunch for most flies, and that seems enough. Al Caucci has always been a fan of very thin bodies, as the real bugs aren't typically as fat as some comparaduns are tied.
