The quietest is a two piece attached directly to the bow. I just bought a Bohning and so far I like it pretty good. I forget the name of it but it' s the one with the aluminun bar instead of the plastic. I took off the top arrow holder and took out the rubber insert and installed foam for fixed blade heads. I like the Bohning cause you can move it up or down the bow so the ends of your arrows don' t stick down too far.
