If the string suppressors are worn out already, has added vibration, and his draw length is too long..........his bow is obviously out of spec..........he needs to check his ata,bh, and cam timing !! Spec's are much more critical on a string suppressor equipped bows........than a single cam without them !
Spot-on. And the SL type cams (whether they are SL,SL2,SL3,HP, OB, OV, etc) are even more critical..supressors or not. JUst goes with the territory. One twist out turned my OB from a super quiet smooth shooter into a twanging suppressor destroying beast.
Also, make sure that
A) the cables are in the correct slots in the roller guard
and
B) that the strings and cables are on the correct attachment posts. I've seen a few dealers who don't know a whole lot putting the cable on the string termination peg or vice versa on an SL type cam since they are so close together. This will make them feel extremely hard to draw and throw things out of whack.
SB is a sweet shooter...could be a lemon, or just a poor setup..but thats not normal for any mathews bow.
