Ray, if you've seen pics of Don Gapen's original tie, you know that the head wasn't a big ball of spun deer hair. It looked to me to be more like an enlarged version of an elk hair caddis head- just lash the hairs down, and clip the butt ends a little longish. His fly would sink, I believe, and that's where he wanted it to be. But for a big-head muddler, your yarn works just fine. The late Gary LaFontaine felt that the spun and clipped deer hair emitted sonic waves that the trout could sense, but I'm not going there right now.
