Crippled CDC and Elk

Fly Description

The genetic baseline of the fly is the classic CDC & Elk, designed in 1992 by the illustrious Dutch fly tier Hans Weilenmann. Weilenmann wanted a simpler, softer, lower-floating alternative to Al Troth’s iconic Elk Hair Caddis. He removed the rigid palmered rooster hackle entirely, replacing it with a single wrapped CDC feather.While Weilenmann’s original fly was styled as a caddis, it frequently fooled trout during mayfly hatches. Recognizing this cross-over potential, fly tier Bruce Salzberg (a close associate of Weilenmann) modified the anatomy specifically to target crippled, stillborn, or emerging mayflies trapped in the surface film.
