Natures Spirit Select Sculpin Wool is a go too for streamer tiers. The wool is pre-carded so that you don't have to. Making this material that much easier to tie with. Coming in at 6" or so, trim it down to size or use it at the full length. Then trim to the style or size you want if you want a trimmed head. This very plush material is also the best way to make streamers as with how we treat the wool, it keeps its shape while in the water, yet collapses when a fish hits it, giving you the full hook gap for a better hookup. Also works well as a dubbing or to mix with your favorite dubbing.
