In reply to pchaggar:
I was there last week and climbed all of those except the Breithorn. Lots of snow - and ski tourers - but by our last day on Friday it had consolidated into fantastic neve. The traverse of il naso is in great condition - steep but good snow (rather than ice) on the west face and a deep easy track on the east side. Corno nero by contrast was 50-degree ice.
Have fun!
