That is an approximation of my CDC caddis, except I tie the CDC all on top as a wing, and use, if possible, whole feathers rather than trimmed fuzz. And yes, it slimes after a certain number of fish. That being said, it can be tied in a minute or so, and I can easily swap out for a new one while mine dries out. I also prefer to tie the wing a little heavy, so that it retains its shape and can be shaken out with a few false casts. Also easier to see on rough water.
