I prefer to use the CDC for Spinner Wings on 32's or for #32 emergers; otherwise Hackle is much preferrred !!!!!
I don't see it as a fetish, as much as simply matching an important hatch. Midges vary from the small (size 32 or splitting the fly tying Atom) to large hook sizes and there are so many species that are overlooked. It is even more amazeing that large trout go for this (Hor' Douvres anyone ??? :ugeek: ) People still look at my #32 patterns and ask me what I catch on this. When I say large trout, they look at me in disbelief !!!! I use what works, and if CDC works better on a certain pattern....then fine and dandy !!!!!!
