Try not to get too tied in knots over the choices available. You won't find a group of folks that are as big a bunch of gear whores as hardcore archers generally are, and the bigger a gear whore they are, generally the more vocal they are about how one bow is soooo much better than the next one...These are great guys to buy a used bow from!

They upgrade a lot!
Practice shooting like you are going to hunt. If you are a tree stand or ground blind guy, it really does you no good at all if you are not a great shot until the middle of your session.
For the sake of the exercise, figure out what you will feel like, after sitting still for two hours or so, in none too warm weather, them you have to take an odd angle shot from a cold start, with an elevated heart rate. Unless you have nerves of steel, and don't get at all excited when that big buck walks into sight, anyways. Try practicing, wearing your hunting clothes, too.
Boils down to having to be able to make that first arrow work, rather than the following forty or so. If you have to struggle to pull the bow from a cold start = too heavy. Speed is good, but all the speed available ain't worth a pinch of excrement if you have to fight the bow to draw it from a cold start! IMO. But that's about hunting...
Talk to some of the dealers at the archery shops. Go to the ones that have a range, that can allow you to try the bows! Try not to get too tied up in the oneupmanship that the advertising flogs.
Modern bows are pretty easy to pick up and shoot reasonably well. Much like a modern rifle. But if you want it to really perform, you are gonna have to learn a few things about technique, about tuning a bow, and about practicing what works for you.
Personally, I liked practicing the first few shots cold on arrival at the range, sitting in a chair, trying to draw as smoothly as I could. Slow and smooth, like I was being watched by a deer, eh. IIRC, my draw weight is set around 62 pounds, and it feels right to me. I can't estimate range for a pinch of youknowwhat, so I bought a rangefinder. I spend a lot of time ranging the surroundings to sort out my maximums, and my range markers.
