I have modified a whisker biscuit rest by flattening both sides of the rest as it had been described in the section" Tech Tips" on the Carolina Archery Products website. The bow that I was tinkering with was a Martin Fury. Using speed balls, a string nockset, and judicious timing adjustments this bow@67# with a 385 grain arrow shot 305FPS through a whisker biscuit. The night before using a tm-hunter prong rest the bow was just breaking 300FPS with the same arrows. I was shooting the bow with fingers in both cases, if I were using a release the speeds probably would have been higher. The point is you can get some speed out of this rest in you want and still have a nice quiet rest. These rests are simple to set up and tune, there is none of that trampoline nonsense adjusting launcher tension and nockpoints till you have achieved proper liftoff. I don' t miss any off the torn fletches I used to get, or the noise that comes when your arrow hits something solid before it leaves the bow. I believe that people are smart enough to see the difference between products and how they perform in real life situations. In real life the biscuit works real well, ordinary people can set it up, and it doesn' t take a commitee to figure it out. If someone chooses to modify their biscuit I wish them every success in their efforts. For myself I' ll stick with it as is.
