For a hunting bow don't buy an aluminum riser, they are just plain miserable in the cold. I know little about compound other than they are easy to hold on full draw. I hunted with a bow in the 1950's, 60's and 70's pre compound era for both big game, small game(even pheasant) and belonged to a archery hunting club. I started with a ParX 50# bow, aluminum grip and magnesium limbs, it was the coldest bow to hunt with, I tried wrapping the handle with sheep skin, you name it the cold just seemed to seep into my hand no matter what I did, hated that bow in the winter and bought a Bear Grizzly 55#, best thing I ever did as far as archery hunting.
I did end up with a compound in the early 1980's a fellow traded one in on a rifle at my shop, I believe it was a 60# Martin, so easy to hold on a full draw and accuracy was unreal, I could keep arrows in a paper plate to 70 yards, as good as shotgun slug of the day. I only kept it for a short time as I could no longer archery hunt for deer.
I did see one of the early Kodiak Magnums with the metal strip in them delaminate in a fellows hand at one of our club practice sessions, it took a lot of stitches to put his hand back together.
