O.K guys hers my question: I shoot a Z7 extreme @ 64lbs with a 28in dl. Im shooting Victory V force arrows that are 350 spine. They weigh in @ 376.5 gns and are 26in from carbon to carbon. On the chrono they topped out at 280fps. Am i overspined and if so des that hurt performance any? Its my dedicated hunting rig and I want to get the most I can out of it at that draw weight. should i drop to a 400 spine shaft?
