Simple solution I learned at my local pro shop for the draw back noise of a biscuit. Take a piece of mole skin about 3-4" long and biscuit hole wide, set it inside the arrow hole and fold the ends down over the front and back of the rest. Your arrow now will rest on the mole skin and you'll be dead silent when drawing back. I drew on a doe at 8yds while sitting on a pale on the ground with the mole skin in the biscuit and she never knew I was there. It'll only last about 25 to 30 shots so practice without the mole skin. Before you go out hunting, slap that little strip in and you're set. One last thing, you'll have to shoot with the odd vane/feather up so the 2 even will clear the the mole skin. Otherwise if you shoot with the odd down it'll come in contact with the mole skin and throw your arrow out of whack. Worked superbly for me, I hope this helps you.
