The west coast sinew backed bows were works of art, as well as their arrow making skills, but I can't for the life of me figure out how they came up with their shooting style. I have made a few of their bows, and tried shooting that style, but couldn't catch on, but thumbs up to Ishi ,and his neighbors. Check Billy Berger shooting one on utube. Master craftsmen of the bow, and arrow. Then their were the "Turks" and Mongols with their siyah bows. Some of them shooting 900 meters plus in their flight shooting games which would put them in a class of their own. The bow, and arrow has an amazing History.
