In reply to Martin Hore:
Well I read it too, wasn't there argument along the lines of we deliberately sacrificed some strength to make the lightest nuts out there. Not that they definitely won't break in some scenarios other nuts will not.
The argument about gate open wiregates being 7kn is not factually correct, go and look at the DMM site, the only non locking biner that has a gate open strength under 9kn is their oval racking biner. I remember reading some text from them in the past regarding how they had deliberately designed their kit to be stronger than 7kn gate open, as gate open loading is not something we as climber can fully control and is quite common and DMM didn't consider this strong enough.
I guess if I need a minimal set of something light to get me out of trouble (for example euroice) or perhaps I'm shaving every gram for some mountain route or another these could be just the ticket. But for me, for my work horse UK trad gear I'll be sticking with the full strength slightly heavier kit.
