Joe,

You do have to be somewhat careful about where you trim the biscuit. If you trim too much off the back or front (even if you don' t cut the slot), the arrow can fall through the bristles. Since I trimmed a fair number of bristles off the back of my biscuit, I would have weakened the bristle' s support too much if I had made wider slots. Fortunately, your mistake only cost you $10.00 for a new biscuit. It' s pretty easy to trim a little and shoot to test, then trim a little more until you have it just like you want.
