Quiet good. The rock quality on the rest of the route was better but I did break off a small knob about 7m before the finish with my foot. I was annoyed at myself because it seemed like a relitively good handhold and there were plenty of other places I should have put my feet. But it's still doable because there is a crimp above it.
Gerd who led it, said that he didn't think it deserved the stars it got in the guide.
Oh, and don't do it at sunrise! It gets about 1hr of sun down the gully just after dawn and you can't see any holds on your right.
There's not much more info I can offer. All I know was that I was happy to be on second!
Probably worth doing if you're running out of grade 25s.
