I have some other most costly slings (some custom, some nice leather from several companies, a few M1907s, as well as Blue-Force Vickers, and different styles of Magpul, some that can be configured in different manners for different carry styles) but the two that I keep coming back to are the simple, cheap, and effective Outdoor Connection SuperSling (I prefer the wider "SuperSling 2" for most rifles, but have one or two of the 1" ones as well)...I literally have dozens of these things and for more precise offhand shooting the Galco Safari-Ching slings (they're rather spendy, but good).
