In reply to ned taylor: I have Edelrid 60m dry treated Merlins - 8mm in diameter.
Wearing fine, handle well and the dry treatment seems as good as anything else I've used. Happily used just the one in winter (naughty I know)and they don't stretch anything like the Icelines. All the stats added up for me when I went through them all.
As far as belay plates go, I bought a spare Buggete in case someone wants to use a narrower one but I use a Reverso fine, my mate uses a Bug and no one has noticed any slipping with their usual device. They've been fell on too.
I much prefer them to my mate's Mammut Genesis to be honest but I couldn't tell you why.
