I have an 08 synergy XT at 29" DL and it says i have the #3 module. My question is when i got my bow the birth cert. said 71.4# with 331 fps (350gr arrow) and the paper work that came with the bow said that the drawstop should be set at the 4 position for 77% letoff and such. But when i took my bow to get a peep put in we measured the draw weight and it was at 64# and the drawstop was set in the 4-3/4 postion (very short valley). So we moved the stop to the 4 postion but now at 73# with 380gr arrow only shooting 295-300. Does the stop effect the velocity or do these numbers seem ok. If so, how should i adjust the drawstop for optimal perfomance. Thanks for the help!
