I am on my second Whisker Biscuit. I didn' t like the first one too much, and got rid of it. Problems were the noise that you mentioned, and lack of accuracy.[:' (]
Now I am using one that I have cut a loading slot like the newer versions, and also trimmed the back flat, following the instructions on the Carolina Archery Products web site. The rest still is a bit noisier to draw an arrow across than some other rests, but it is quieter than the unmodified one was. The accuracy of this rest is much better than the first one was. I am shooting as well with this setup as with any other rest I have used, including drop aways.
I have heard it mentioned that the biscuit often gives bullet holes when the tune is not really right. That is what I found to be true as well. I had to move mine around some to get the grouping right. I checked it by group tuning, shooting with broadheads, and also by shooting a few different types of arrows to see how close they would shoot compared to each other. At some settings when I had been getting the bullet hole, the grouping was not so good, and broadheads would not group with field points, and different brands of arrows would impact at significantly different points. By making small adjustments, mostly with the broadhead-field point patterns, I got the thing tuned pretty well.
If you are noticing the arrow " kicking sideways" then I think some fine-tuning would help, and perhaps there is torque in the grip that is affecting the arrow flight. Even though I am pleased with the biscuit for now, I would not say that they are the most forgiving of all arrow rests.[
