Bottom line and easiest way out of this for those who feel they are getting " shafted" (get it, arrows, shafted, oh, never mind )---buy three dozen arrows, sort thru, match weigh shafts and components, assemble them, match weigh them again. Keep only the ones that match. Shoot them thru a hooter and individually tune each one to hit the same hole at 20 yds. If they do not, put them aside also. When you come to find 12 that hit the same hole, stop there, put them in your quiver. Sell the rest on e-bay as brand-new arrows like most knowledgeable archers who have access to a hooter do.
