Although the new B2 biscuit works great, I had no problems with the old one. With the old one, I trimmed a few layers of bristles off the back (part facing archer). I then made sure I was shooting some durable vanes, like Bohning, that were properly glued. I could shoot these arrows all year without damage (if I didn't screw them up in other ways). At least the damage did not come from the biscuit. On the old biscuit, I also recommend taking it out of the slot and cutting a notch for easy arrow loading. There is already a cut in the bottom of the biscuit ring, so just snip a 1/2" section and spin to 10 o'clock when putting it back in the slot.

No need to change rests if you really want to enjoy the other advantages of full containment rest. This rest simply excels at keeping your arrow in shooting position, no matter if you're stalking or in a stand with the bow on your lap.
