There are guys on here shooting recurves and longbows from their saddles. No compound bow you find will be longer ATA than a recurve is tip-to-tip.
You might find that, say, you can comfortably handle 70# all day on the ground, but in an awkward position from a tree 65# or even less is more comfortable, and you can thus hunt with it more confidently. You don't have to impress the Instagram archery bros with how much weight you're pulling, just shoot it well.
