RE: Easton ST Epic Arrows
I shoot 31" 340's out of a Bowtech Tomkat at 66lbs, 2" Blazers and Limb Driver rest. I got lucky once (I thought) and picked up a dozen Epic 300's and a dozen PSE Carbon Force 400's dirt cheap (Both one step up in stiffnes from the Epic 340). Neither of these flew better than the 340 Epics. So much for the "stiffer is better" theory, both stiffer spined arrows consistently flew left. For the money, the ST Epic is a great arrow. 340's should be perfect for you.
