I was getting a noise that I finally pin-pointed. My string and buss cable were touching each other, right above the cable-slide, where they cross. I installed a new slide (white teflon) and the noise went away. It took me a while to figure it out, but I used the method that "hunttones" uses. Hold the bow firmly by the handle and then bump the edges of my limbs with the heel of my other hand. It will tell you pretty quick if anything is loose.
