My ' 02 single cam Pat is super quiet with cat whiskers on the string and cable and the added limb savers. My ' 03 pat Dually is not as quiet as my single but is very much acceptable for hunting. I recently moved the Bowtech VibraBlocks down to the limb pockets as suggested by others and it did make a notable difference. I' ve never tried the Sims string leaches and compared them to cat whiskers but some day I' ll give it a go. Good luck this season, Russ.
