Smoky Mountain Candy help

[Dawgvet]

I have been wanting to tie up some of Walter Babb's Smoky Mountain Candy flies but had a question about the tailing material. The article on LRO mentions "stiff deer hair from the back or groundhog tail". I've got a good amount of deer hair, mainly for tying comparaduns and a small patch labeled "woodchuck" which I think is what Yankees call groundhogs What do you all use for Wulff style flies when you want them to float the best? Any help appreciated.
Thanks,
