My new bow was making quite a racket when I first started shooting it. Being so new to traditional I didn't know I could tune my brace height so I just threw some cat whiskers on and what a difference. I placed them about 1/4 way. I installed mine using small wire ties. No, not the kind on bread bags, the kind used to hold wires together. They are easy to use, hold the silencer in place well, and are easy to slide up and down the string. They also go on faster than tying them on.
