I have a MARTIN PROWLER (2005) and the draw wt is 67 with 30 inch draw, I have been shooting easton epic 400 carbon arrows but it was set at 63 pounds. when i went up to 67 pnds and took it to get paper tuned it will not stop tearing high. Do i need to switch to epic 340 arrows or what. the bow has the dyna cam also.
