Don,
I have tied and used the Soft Hackle Woolly Worm and you need to tie some up. It works very well on trout and bluegill. The tying instructions are good and it is fairly easy to tie. The only thing I have changed is that I tie it in "reverse". By that I mean I start the dubbing and first hackle at the front of the hook so that I end up with the bobbin holder and tying thread at the rear. That way I can palmer the thread through the hackle and body to the front and then do my whipfinish. I only do that to reinforce the hackle. I do that on most of my flies rather than use ribbing wire. I am not recommending that to anyone. It is just the way I like to do my flies. As long as you make sure to use thread that is is pretty much the same color as the body, you will never see it. When I have used ribbing wire I find that the small teeth of the fish will pull the ribbing wire towards the bend and ruin the fly. The thread seems to sink into the body more and my flies hold up better. Just my thoughts and my way only and nothing more...

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
