In reply to southernclimber:
Hey! Very very nice classic. If you are solid at the grade, I would say that it is 2 pitches of "trying to put in a little effort" and the rest is very good quality climbing. However, don't underestimate the length of the route and the descent as well.
June might be a little early in the season to avoid snow. The route can stay wet for a long time and I would certainly bring an ice axe along. You can always give the Sasc Fura hut a phone call (0041 81 822 12 52)
The approach is really easy. Sasc Fura hut by foot in 1-1,5 hrs from the parking (toll road). If you walk a little further, there are tons of good bivi spots.
There are two options for the descent:
-abseil along the North Ridge, not easy to find and pretty long. (Option is to do the North Ridge prior to tackling the Cassin, to acclimatize a little and to find ab- stations)
-shorter descent to Italian side (2-3 hrs to Gianetti hut, and hike back the next day)
Enjoy
