In reply to DreadyCraig:
I'm not sure about the exact carabiner but I have some of the other mammut carabiners and due to the fact they are made by DMM they are very nice.
If I liked the DMM shield I'd be quite happy to buy some. Also, needlesport are really good and trustworthy in my experience so I'd be happy to go with what they say.
I picked up a few of these extenders from needlesports. very impressed with them.
the sling has a rubber insert which ensures that one of the krabs stays in an easy to grap position. very neat and nice and light too.
I bought a couple recently (Shiny! Cheap!) and hope to use them for the first time this weekend.
Armchair experience: they rattle. There's a captive rivet at the tip of the wire gate, and it moves enough to rattle. There's no way I'll be able to hear this when I'm outside and have a rack of other gear clanking around, though.
