My Canadian guide usually sends me two dozen Epic shafts a year to sort and fletch for him. Out of those he usually gets 12-14 "A" arrows a few "B"'s and the rest "F"'s. This year he sent me two dozen ICS Hunters to sort and fletch. After sorting for spine deflection, 360 degree spine consistency and straightness I sent him back 21 "A"s and 3 "B"s. That's a pretty good batch of carbon arrows. At almost half the price of the arrows I shoot!
