In reply to Jaylaz:
The climb was great. We've had settled high pressure in the Alps for the past week along with lots of sun no snowfall but quite a low (330ish) freezing level (and all looks to continue for at least a week) so all the rock is dry, the snow is in great condition in the mornings, but definately on the leaner side.
The glacier approach to schalihorn was much more straightforward than I thought it would be - it's possible to spot a route around the worst crevasses from the ober alschorn before you descend. Theres then a 40-45 degree snow face to the summit. This was in great condition for us, but parts of it could become a icy in time. Then again there's many lines you could take up the face and it's probably only PD for this bit
Schalihorn traverse was great scrambling. It is a little loose and complicated but good rock on the crest and it's mostly downhill so not tiring. Managed to avoid all abseils.
The bivoauc hut can sleep 8 but looking at the book it's rarely visited. There's loads of gas there and some limited pasta etc. Snow 50m down to melt and we found a small stream.
Snow for the Weisshorn N ridge was great likewise for the bishorn. There are 3 bolted abseil points on the grand gendarme too.
