These things are ungodly light. The biners way 29 grams each, so the sling only weighs 7 grams. You really can't get much lighter than that.
They are also wiregates. Recent research on dynamic falls has proven wiregates to be much safer than traditional gates, the traditional gates are prone to open under heavy movement. Don't believe me? Take your wire gate and your normal gate and smack them each against your hand, with the gate being on the opposite side you strike. You'll hear the normal gate "click" once the gate snaps back into position, but the wire gate will stay put. It's due to the extra weight of the gate! So wires are the only way to go.
In addition, you're only spending $13.60 per quickdraw with this set up. Sure, the heliums are better, but not that much better. For the price, there is no better quickdraw!
