In watching of it:
1) Bow weight needs to be quite low.
2) Tab needs to NOT have a big melted edge in your mouth
3) Draw should be set up such that your tab pulls straight out, CANNOT have your bow at an angle to your jaw (you'll shred your cheek in a heartbeat)
4) Might have to adjust your peep height to match new "anchor point"
I personally wouldn't do it. If you find yourself with a mouth, tooth, or jaw injury from overweighting or creeping your cam, you'll be in a world of hurt. It's a big difference if you're permanently disabled, then you have to do what you must, but for someone that'll potentially miss ONE season due to an injury, it wouldn't be worth the risk of injury.
