Good luck figuring it out...it can be maddening! [/QUOTI was talking to a very competent FITA shooter earlier this year who told me he generally only gets 8 or 9 shafts out of a dozen that are usable for his purposes...the shafts he was talking about are the Easton x10...next time you think you shoot expensive arrows take a look at the price of a dozen of thoseDDave
