I've been using an Uncle Mikes Mountain sling for years and years. I like it because it is a simple 1" thin nylon, adjustable lightweight sling. It has a section of rubber like material on it to keep it from sliding off your shoulder. It's detachable swivels are stout. I like it because it doesn't "swing like a pendulum" and mess with my aim if I shoot offhand, or make a snap shot rather. I also like it because I can remove it, roll it up and place in a pocket if I am in the puckerbrush. I have friends in Texas who like the big leather slings with decorative carving and big thick leather pad for the shoulder. They use it from the pick up to the blind ( from 50 to 100yds away) and even use the pad to "pad" their forearm on the window edge, ha. As an Army vet, I really got used to the M16's little nylon sling so I guess the Mountain sling is just an upgrade on it. I just don't like a heavy, swinging sling when shooting offhand and I also keep the weight down even when using a butt cuff elastic ammo holder, I don't want the handling characteristics messed with. As you can tell, 99% of the time I hunt with what the Brits call a "stalking rifle". A heavier, bulkier rifle for prairie or long range can sure benefit from a thicker, wider sling as I don't shoot them offhand like that. I'm more of a sitter/crossticks kind of guy. I've only been able to shoot prone a few times, due to terrain, even in South Africa and Namibia.
