This is my take on the WB and the question of speed loss. I don't know why anyone evens mentions speed loss. It's insignificant and would not affect sight setting, even a little at hunting distances. I've even tried hard helicals and only lost 5 fps. Once again, not worth talking about. Only speed freaks who eek out every fps, regardless of what it means, would care about a couple fps. I once cut notches (for the vanes to pass through) on a trimmed biscuit and gained 2 fps over a conventional TM hunter style rest.

The true beauty of the rest, the area in which it excels, is in it's ability to have your arrow in shooting position at all times, no matter how you're holding your bow or what type of hunting you may be doing. If you bump a branch, no noise comes from the biscuit. The bristles act as a silencer for such bumps. It's sturdy, simple, has no moving parts and would be difficult to damange beyond use, in the field. As a target shooter or a 3-d rest, it brings nothing special to the table, but as a hunting rest, it simply excels at the things that are important to most hunters.
