Do you weigh each and everyone? If so do you group them into same weights? Isure do!I want all my arrrows (I build my own) to weight no more than + or -one grain of my desired weight. For example right now out of my Switchback I am shooting Gold Tips XT's 7595at 29"fletched with quickspins and tiped125 grain fieldpoint/broadheads. My combined weight is 450 grains, I willallow 449to 451 but no more or less than that for either my hunting or practice arrows. Ifa arrow doesn't meetmy standards and there seems to be always one or two that don't out a a dozen.I don't junk the arrow but mark it for a bird and small game arrow or a long shotrisky 3-D arrow where there is a good chance of loosing/breakinga arrow.
