This is somewhat similar to the Hotpants that I use so much on the Snake but with a few notable changes. The fly pictured in Snake River Autumn is looks more spey style than the version I usually use on the Snake. I believe that I included a Hotpants in my submission of six. If so, I will put it up once Juro gets it scanned in.
I agree with you on the color combo though. I will fish this combination in all but severely low visibility and in all light levels. The three color combinations I usually rely on are Purple/Red, Orange/Red and Black.
