Hi, Gandolf

I think it's hard to go wrong by covering the caddis cycle with Hans' CDC & Elk and LaFontaine's Emergent Sparkle Pupa and Deep Sparkle Pupa. Maybe throw in an X-Caddis or two. The most effective fly I've used in 25 years of fishing the Cimarron has been a caddis larva imitation that is nothing more than a scud hook (probably not necessary - a straight hook would work just as well, I'm sure), bright olive dubbing, a wire rib, and a head made of picked-out black hare's ear fished along the bottom.
