Excellent Marty!
i buy mine form various places. It’s so hard to find the fine bucktail I like from the fly shops. I’ll rummage through ten tails or more before I find the one I like. Then grab a piece to cut to length. After I cut it off I grab it by the tips with my left hand, then take my right hand and slide my fingers from left to right with a light grasp. This removes the smaller, shorter, under hairs that cause problems. Only use the hair stacker if needed.
Good bucktail is so hard to find!!
