Didn't even know how good this was till i got it in the mail - Mammut Contact Sling 8.0 mm

This sling is perfect. Super light, compact, 22kn strength. I have yet to see the durability, but unless you are really putting these through their paces, this is the one I would suggest for anyone; sport, trad, or otherwise. It comes with a handy chart of knots vs. strength loss which I found useful. I use this for top rope anchoring and I would call it bomb proof (assuming your anchors are good that is ;] )
