Been thinking about buying one. But on another sight several are saying it’s hard to “ tune “ prime bows. Always a problem with rest position not being able to get center shot. Always need to offset cam timing, to get level nock travel and a few other issues. I am not at all familiar with prime and am wondering if others have issues , or are these guys just prime “ haters” ? I really liked the prime 5 more then any of the other bows I have tried so far, but don’t need a problem child. Only have the Mach 1 left to shoot.
