A bow quiver that clamps on the limbs at or near the fade outs can really quiet a Grizzly down. Even the old Bear spring arm quivers can work. Some bows just have a noise that comes from the limbs and a quiver will act like limb savers. I recently "tamed" the noise out of an R/D bow with a two-piece quiver at the fade outs, and I had an old Grayling Grizzly that needed the same treatment. Once the quiver was on the old Grizzly it was nearly silent. Once it is quiet, a Grizzly is a great bow.
