In other words, would 2 suppressors or even the one suppressor on Hoyt's bows actually be slowing the bow down? If you had a suppressor to cut that movement down to an 1" past the resting position, would that slow the bow down 10 fps just as dropping an inch off your draw length does???
Quite contrair, once the bow has passed the resting point, it is no longer producing forward energy, and that's why by installing an STS type dampner, some guys actually see a slight increase in arrow speed, breaks the arrow away from the string quick and clean!
