Ahhh... a question near and dear to my heart...the Kwyk Styk!
Try bringing your brace up to 7 3/4" and depending on the your bow length...My two are 56"... divide the length of by string by 4 and put your silencers on the quarters(1/4-3/4)....if that doesn't work. Divide the same amount of silencer material and also put silencers on the 1/3's....
One of mine likes the four selencers, the other is fine with two...but both the same amount of material.
Hush puppies are the best I've found...also a little bow hush on the ends will help with string slap in the limbs.
If I've confused you, I can show a picture of what I mean......
