did a route on nazomi a few years ago (nearly to the top)
looked like a good weather day so did it from gardner hut. guidebook said the obvious couloir was grade 2 so we did the obvious couloir (the one that links nazomi to the south ridge of cook). when we got back to the hut found out its supoosed to be grade 4. funny because 2 of us were comfortable soloing grade 4 (70 deg ice) and the other guy thought he'd be ok soloing a grade 2 couloir. think it was bit exciting for him. ....fun times...good route
