Vickers.
If you run QD's, you can add an IWC 2 to 1 point triglide if you desire.
I wish they made one with an anti-slip strip on the padded model for use on a hunting rifle.
I just got a Viking Tactics VTAC ultralight padded hunting sling that has an anti-slip pad that I hope works out.
VTAC has some new ultralight slings with hypalon end straps that are worth a look. That said, the Vickers has an advantage in that it doesn't have a free tail and excess strap is always captive.
