    I have been given six ST Epic 340 arrows, but my usual spine is 400.  I shoot 150 grain heads and Flex Fletch 360 vanes.  My HeliM is at 64 lbs.  I don’t have the software I’ve seen used here, and the charts I do use don’t have a 150 grain option for the heads.

    How long do these need to be to get proper spine and good flight?
