Scott, haven't done any tyin' with elk but maybe Dusty has?
What we need is the coarse hollow side body hair from a big oldest buck you can kill or acquire from processor.
Whatcha think Dusty?
Texas bucktail has best texture for streamer flies but Northern body hair best for bass bugs.
I like body hair better than belly hair but does have some use.
Beggars can't be choosers

- we'll tie 'ya some bugs!
