Hey guys,
I'm surprised no one has mentioned a 3-point sling yet (tactical type, not a 3 point Ching sling).
I'm not sure what brand they were, but the one's we had in the Marines were able to be used like a 2 point which is nice for the reasons you've all mentioned. Unless we were on a hike or some other admin role, I'd almost always release the forward fastex buckle and use it as a single-point for field work. Seems like the best of both worlds, but I've never had experience with a dedicated two-point besides a cotton USGI or M1907 sling...
