I go through quite a bit of deer and elk hair, as I use it often for various dry flies and emergers. Last week I was placing an order from Blue Ribbon Flies, and I saw that they had early season cow elk hair available, so I ordered a piece. This stuff is great; fine hair with nice even, unbroken tips and the perfect color for medium to lighter colored flies. I tied up a bunch of tan X-Caddis with it, which is a pattern developed by Craig Mathews of BRF, and the results speak for themselves.
