I just read something that I hadn't heard before regarding arrow spine and longer arrows. This was in a book on shooting primitive bows by Paul Comstock. I don't have the book in front of me so I hope I don't misquote. The jist of it was that the native americans used super long arrows to be more forgiving of spine. They would only draw to maybe 24-26" and have 36" arrows. He said that the closer the balance point (or FOC)was to the bow when drawn, the more forgiving the arrow was to spine and the quicker it would recover from archers paradox. So the indians could shoot a variety of spines from one bow and they would all shoot reasonable well. I suppose that shooting an extreme FOC arrow would do the same thing. I have noticed with my kids that they can shoot my arrows that are way overspined and long for them and they fly well so this seems to have some merit. Has anyone else heard of this or noticed this?
