I might as well share my OPINION as regarding old school cat whiskers... On my PSE Triton that I used to shoot I had string leaches that eventually started to shred.. After noticing a difference in sound I decided to pull out what was left and then tie on some cat whiskers.. My bow might have quieted down a little, but the bow was definatly quieter with the string leaches as aposed to the whiskers.. For me, whiskers get a thumbs down... STS gets a thumbs up... Like DaveC, I am definatly not an STS salesman, but im not ashamed or shyto promote a product that actually works for me..
