A while back I bought a dozen POC shafts, tapered them, and cut to length. Before knowing any better I glued the nocks on without any regard for alignment with the grain. By chance, a couple were done correctly. Some are rotated 90 degrees from ideal, and others anywhere in between. I read somewhere that the arrows are more likely to break when the grain isn't running perpendicular to the riser. But my question is HOW LIKELY are they to break? They're spines properly for the bow and are just small game/stumping flu flus. Around 600 grains and only flying like 170-175 fps. I'd really like to shoot the rest of the arrows I bought but don't want splinters in the hand.
