hmm...personally I'd sling my arrows (jack bowyers chief side quiver) and wear a daypack or bison pack. For me the bison pack is a no brainer..the things rock beyond anything I've worn yet! They do cost a bit more, but as the saying goes you get what you pay for!
I wear a sling a LOT while fly fishing...and love them! but they do have limits and hunting imho is not a place I'd wear one. Maybe its speculation on my part. but in the grand scheme of things I'm going to have to take it off anyways to get to gear, plus set everything down etc. Its just easier to be set up that way to begin with. So the benefit of sliding a sling around is really gone.
Slings ride great...to a point. When I'm doing more remote trips, and I'm carrying a load, I'm not all that happy with my simms large sling. When I have a wet hoodie strapped to it (bottom has straps for this), I'd rather have my bison pack all day long!
A sling may be a better option for a guy like me wearing a side quiver (with the sling on your back), but there comes another problem, multiple straps. Ie sling, quiver, binos. I encounter this issue when on remote backpack hunts up here. It's a pain even with a bino buddy harness.
The other half is a heavy sling is a pig to get off when you have a pile of gear on, binos etc. And over the miles becomes uncomfortable as weight increases.
I can go on, but these are the initial thoughts I have on wearing a sling for the things that I do myself. Sorry if I'm thinking out loud a bit here at your expense.
