Yes, an experienced knapper can make points at very near the same weight. Arrow spine is really important to good arrow flight especially with primitive arrow material and a selfbow. I usually make a set of arrows, shoot them all to see witch ones shoot the best out of the bow I plan to hunt with. Once I narrow it down to six arrows or so, I will put points on a couple of them to see how they shoot, and leave fildtips on the other to do most of my practice with. Then before season, all the arrows get new points.
