I recently switched to the Magpul MS2 sling... and I love it
I've got one of the cheap clones, so cant say yet weither or not it will hold it's tightness or length settings in use as I haven't owned it long enough yet.
mine stays mostly in 1point ... but the quick 2 point option is nice for slinging weapon snuggly to my back (weapon hit, transiting, or dmr/sniper long arms) ... lets me stay with one sling and use it, make it 2nd nature for all my weapons, instead of the idiosyncrosis of multiple slings for different weapons.
