OK my fishing buddies fished circles around me this weekend using the fly pictured below. Being a die-hard-gotta tie my own-fly tier, I can't bear to use a store bought fly. I bought one below just to copy it but I'm stuck because I don't have any idea how to make that body. My local shop guessed the body is made from "trilobal chenille". Can anyone confirm that? And if so, where the heck do you buy that stuff?
