When Hillbillyhunter turned the machete loose on his brand new biscuit he reclaimed 6fps of the speed he lost when he went to the biscuit. When he read the chrony I assumed he was going to cut the whole thing off. Trophy Ridge tells you there is a speed loss when using their "newly redesigned" whisker biscuit. They claim the loss of speed is less than what Hillbillyhunter experienced with his original Carolina Archery rest. I highly doubt Trophy Ridge would say there is a speed loss if there wasn't. The laws of motion are relatively simple. They also agree with Trophy Ridge, Hillbillyhunter, and countless others. I don't shoot a biscuit on my hunting rig because of my perceived accuracy issues with the rest. When I set up another bow fishing rig I will probably be going with a biscuit as I can't hit the damn fish anyways ......and a few feet per second makes no difference when you're shooting a monster arrow pulling a string. .
