Anyone in love with their sling?

I like off-hand shooting the most and shoot mostly at a 25yrd indoor range. But I want to vary shooting with a sling now. I've only use basic 2-point slings in the past with the old simple forearm wrap. Basic 2-points at Wallys for < $10. Don't need a pad really since it not a hunting situation.

But what do you folks use and like?
