RE: Native Americans...
I started out with a recurve when I was a kid. (many, many moons ago) I shot it nearly everyday. Mostly roving type shooting. Shooting at leaves, butterflies, you name it. I could shoot that bow great. I killed many small critters with it.
That is the 'trick' with primitive/trad bows. Shoot it a lot. Shoot it until it becomes second nature. Don't get stuck on paper and foam targets. A baretrad bow is harder when it comes to consistencythan a compound but you'd be suprised how well you can do without sights and let-offif you are dedicated.
(On the downside, the recurve is probably what ruined my shoulder.)
Having said all that, I much prefer deer hunting with my Bowtech compound and Hind Sight bowsight. [:-]
