Jim,

Try out "Targus Foxxfur" brand craft fur. The fibers are longer than others. Also "Slinky Flash" used with Foxxfur or bucktail is good.

If you are using some kind of craft fur, you want to use bucktail for the wing on top because it will keep the fur from fouling the hook, and it is more bouyant to keep the fly riding right side up.
