First of all make sure you are just touching your decelerator, if you're too far from the string or too close it will make a popping noise. Second of all I have tried all the string silencers on the market, when tied correctly whiskers are to me far superior and safer than anything on the market. Just make sure they are cut short and look like a round puff when done right.

This is the only way to tie on whiskers: http://www.youtube.com/watch?v=Z6WNx...eature=related
There are many that teach other ways, but this is the best way!!
