I've found if you have wide axles, you'll have more noise. At one time I had a wide axle on the bottom limb of my hunter, and had to put string silencers on all 4 cables to quiet it down. I've since gone back to the standard axle, letting the cables touch, which acts like string silencers. I originally went to wide axles in order to seperate the cables, but soon found if I used wide axles top and bottom, the cables still touched. Am now back with standard axles, and keep the cables waxed. Let 'em touch.
