I got your pm but i cant reply so i will have to answer you here. If you can get it at a good price then yes it is the best to tie with, there is no perfect substitute for Polar Bear and yes i do use it a little bit for a few patterns. I just dont buy much and it takes me awhile to use it up, if i used it for what i would like to a chunk would be gone in a dozen flies which would get pricey.
did i mention you can spin the PB hair in a dubbing loop and brush it out then wrap it like a hackle
Well you can and it looks and works great in big Intruders
it works nicely as the "bump" to flare out your other materials. I would like to use it this way more but instead i use Artic Fox instead because its only $2.50 per chunk
