I tend to shoot them and mark the ones that shoot good with a shrpie or pencil, then I can keep track of the ones that hit "most" of the time. Many have said to orient the stiff side, but they haven't said where to orient it, the stiff side of the shoot should be against the bow, opposite the index feather if you are three fletching, but stiff side should go towards the bow. I shoot arrows of all differen lengths and diameters, heavy end forward and tally hoe, shoot em til you know em. That's how I do it. Good luck, dpgratz
