Would you prefer to error on the light or heavy side, in general? In my instance, shooting out of a 45-50 pound bow, and wanting to have arrows matched as best as possible, but understanding that I will end up shooting all those arrows out of a couple different bows which are some pounds apart. I plan on taking just one bow and tuning all the arrows fly their best out of it. Most of my arrows have tended on the stiff side (clank off the bow, hit left of target). Still, I will end of shooting them out of a different bows since I don’t want to make sets of arrows for each bow.
