I've used a bow, typically with a 65 pound draw weight, but I use it more for shooting and targets than hunting.
I would suggest instead of using the forum to go to a good sportsman store or shop that specializes in Bows and archery equipment. There is a LOT more than just draw length that you need to be concerned with if you are wondering about that.
I would suggest starting with a starter bow, or at least a more generalized type of bow, I started with a Bear brand, fourty five pound draw when I was first introduced to archery (always used a compound, never the other stuff myself). I then moved up to a sixty and now a sixty five. I suppose I could move up to a higher weight, but there really isn't a need for what I do.
You'll want them to teach you how to replace parts on your bow. You'll ALSO NEED TO LEARN the correct WAY to draw. If you draw wrongly, the most obvious thing that will happen is that you will quickly develop a bruise on your forearm. It can get worse inclusive of straining your back, and other portions of your anatomy.
The key is to be able to pull without moving the bow itself (keeping eyes on target). However, one thing that you'll need to do also will be to set your sites, and if you haven't done it before, it would be best to have person on person teaching, as yes, one could tell you how to do it here, but it doesn't show (and it really should be shown) how exactly it should be done. The same goes for the correct way to use a bow and to care for it.
For beginning since mistakes are apt to be made, be sure to invest in an armguard. I would also suggest a release, but that's just a suggestion.
Just my thoughts on the matter.
