I've often read that the longer the arrow and the heavier the point, the less everything else about the bow and arrow matters. The Welsh longbowmen probably didn't have accurate spine gauges, or gram scales, but they did have long, heavy, arrows. My limited experience with self bows and shooting off my hand is that a longer than usual arrow with a heavy point will fly consistently so long as you have a consistent nocking point, wherever it is. Doesn't much matter if the tiller is perfectly even, or where you rest your arrow. Thoughts?
