It may sound stupid, but I do not see the need for the thickness of that many bristles in my W. B. Thats why I began to shave bristles out of each side. I figured it would mess up my vains less, and reduce the drag thus increasing my F.P.S. I may wind up ruining this W.B. if I keep shaving it, but I think I will keep shaving little by little, from both sides, and chrony it every so often to check my hypothesis. I figure as long as it still supports the arrow, and is kept even all the way around, I should be able to use it and let everyone know what I find. And if I ruin it, well then I answered my own question and I will replace it. Stay tuned.
