When I first bought my Q2 XL my local proshop installed cat whiskers, conventional limbs savers and "stick on" miniature limb savers to my quiver. In combination with a doinker stabilizer - my bow is extremely quiet. Strumming my string identified a twanging noise coming from my Mathews quiver - the stick on miniature limbsavers took care of this problem. The point I'm making here is to consider all of your accessories as a potential source for noise.
