I have several of the CAMP Nanowire quickdraws and the specs aren't significantly different. I think you can get lighter… I was looking at these a while ago.

33 grams each
Main Axis 25kN
Gate Open 10kN
Minor Axis 8kN
Gate Clearance 27mm
So it's about the same as the Camp that I have… except 2x the cost, but not as heavy.
I wish I had seen these less expensive quickdraws. It would have saved me some money! My needs aren't that demanding.
