Anybody can go to the Bieter website and see that the bow and arrow both occilate as does the nock travel of the bow.

The original whisker biscuit with the full circle contained the arrow 360degrees and helped to tame some but not all of those occilations.

I have never had a problem with the whisker biscuit bending or any part of the rest bending or failing in any way.

I have experienced bent fingers and bent prongs on other designs of rest.

Most bows will shoot a level arrow from the 90degree position on the bowstring if they are set at an even tiller, and that is what seems to work the best with the whisker biscuit in my experience.

Proper spine is what proper spine does. A properly spined arrow will hit the same vertical line at all distances. Spine charts are often a bit softer than the real world needs and its not just when you use a biscuit, that goes for any rest.

Most folks can get their bows to tune with a whisker biscuit and the correct spine arrow. Its not that complicated to do.

I got no regrets from my biscuits!

Good luck hunting! >>>------------>
