i use snowshoe for the body and wings on my green drake spinner spent wing. floats like a cork, in fact it floats so well you can yank it under and it will slowly rise back to the surface of the water.

fran betters used to use it for his usual pattern for that very reason.

i wouldnt try to stack it, cut it to the length you want with scissors, comb out the fine fur and save it for dubbing bodies. ties easier than elk hair, it doesnt flair out on you.
