The whisker biscuit will spoil you when it comes to holding your arrow and having it ready. That is what the rest is doing (or not doing well), 99.999% of the time, and it becomes very obvious to WB users, that it excels at this.

It is my belief that if you have tuned your setup and are shooting the correct draw weight for your arrow spine, that accuracy is as good as any other rest. I shoot in a winter league, and although I' m not a top shooter (probably lots of form flaws) , I shoot as well or better with the WB as I have with any other rest. At my average hunting shot of about 15 yards, I' d much rather have the benefit of an arrow that is always ready to go, then to pickup up some barely detectable, minuscule amount of accuracy that has no effect at that distances my hunting shots are taken at.
