Another thing you can do is get a pack of the Simms Mini-Limb Savers. I think they are around $12.00 for three of them. Put one on your sight, then put one on your arrow rest (if it is large enough to allow for one), and you can put the third one wherever you want it. They will help absorb any vibration, and vibration is what causes noise! I have them on my site and arrow rest, and they seem to work good for me. It isn't a drastic differance for me, but for the PSE sight, it might make a big differance!
