Planettrout, you beat me to the pointing out that to be a true E/c caddis it has to have 2 colors. I will never know what the trout think but to me the 2 color thing must have something to it. The Barr emerger is another example of flies that use 2 colors and somehow it just seems to work.

Byron you could, with a little impressionism, think of the trailing shucks you like on your caddis and comparaduns as a second color. I don't know why it is but it seems to me when I have some kind of color shift in my flies they seem to work better than a single color.
