A.K. Best mentions Gretzen deer hair in one of his books that I have (Production Fly Tying, I think) and in his video Tying Dry Flies. I have not seen any catalog or online mention of this hair which I believe is from the middle of the back on the hide.

I would like to get some of this as most of the deer hair patches I have are great for spinning but flair a lot when used for tailing and wings. Also I think AK said that this is the straightes hair on the skin.

So, where can one get some of this Gretzen hair?

Thanks
