I'd add dont get stuck on a particular brand or the high end hype. Pretty much any modern bow now days makes a great hunting bow. Brands like Mission, Diamond, Limbsaver are a few that have less expensive bows that shoot just fine. I have Z7 and a Mission Maniac, honestly the Mission is my go to bow, it just feels better and is lighter. Both a 72lbs and both are very smooth drawing.
Most bows even the higher end models like the Z7 dont come with a good string, the Zebra is better but not great. I removed the factory strings right after it got broken in and replaced with a Winners choice. The factory string is a good spare. If you spend a little less on the bow it may leave some more money for good accessories. A good heavy duty sight, rest and release are a must for hunting. Your bow can get alot of abuse while in the field.
