Thanks Xmod (GH?),
The routes I'm referring to are the aforementioned 'My preciousss', that is indeed better described as being in an overhanging cleft than 'around the back' of the Cloud Nine wall and another, obviously more recent, route that goes up to the same chains. Guess you haven't seen it yet.
Am I right in thinking that 'My preciousss' is the route up the middle-ish of the broken face, and the newer mystery route is quite close to the arete on the left? Or is it the other way round?
Anybody else know the mystery route?
