As for early native draw weights,there were various draw weights,as there are today.Native people,were in fact people just the same.Some prefered heavier weights and some lighter.No different than anybody else.It has been my observation,that the arrow was of greater importance to early native people,for increased penetration.Great pains were taken to manufacture the perfect arrow,for the task at hand.Recently,Billy Berger,did an experimentand published his findings,in PA magazine.He found,what early native people had known for a long time.With proper arrows,higher draw weights were not necessary for proper penetration,in hunting larger game.Unfortunately,current game laws,often prevent us from useing this wisdom.
