I have the WB's on my huntig bows. You will lose a few fps's but you canshake your bow upside down if you want and the arrow can't fall off the rest. The cammo arrows are a little louder on the draw but your rest will soften up the more you shoot it. As the bristles wear in it will quieten down. I use the aluminum disk for my carbons and it is pretty silent from the start.
