I've used the same yarn for a size 6 rubber legged stonefly similiar to Timmy Doyle's rubber legged tellico.
That fly started as "base" so to speak of a crawdad idea I've had. I'd like to experiment with segmentation on the fly, maybe shellback, maybe some dark flash, rabbit for claws. I need to tie some with weedguards for sure though so I can bounce it along the bottom without worrying. I'll pick up some mohair next time I see it.
