Good advice given! I'm agreeing with 40-45 pounds at your draw. Keep in mind you will more then likely loose some when moving from Compound to Trad., some people don't, but most do. Most bows are measured at 28", so if you shoot 27" you won't be pulling as much.

Along with Become the Arrow (vieo and book), check out Hittem Like Howard - John Schulz, and maybe Masters of the Barebow volume I and II.
