Not to disagree with MOBO buta fewbows i have came across do not like the stsstopper touching the sting... My mathews for instance does not like it.... I had to back it off about 1/16in off the string..It made a noisy thud that i didnt like and backing it off a little stopped this.. Where as my Oneidas, all have them are slightly touching the string... My point is i guess...dont be afraid to try moving it slightly to getthe best results for your bow...
