I use Icelandic Sheep Hair extensively for my larger streamer patterns, especially in all black. It's easy to tie with and I can't see where it soaks up any water at all. Eight inch streamers are easy to cast on my 7wt. Great stuff with lots of movement in the water.

On the other hand, flies tied with long zonker strips of rabbit fur cast like a wet sock and I don't enjoy fishing them at all. Just my humble opinion.
