In reply to fcy5: thanks, I'm going to look into it, though the SE Flank looks like a complicated meandering route. 6-7 hrs up and down?
Mönch SE ridge looks very doable in a day, despite the costs involved in getting up there.
I've seen some pics of the summit arete on Mönch, lookes perhaps easier in full winter condition? In the summer it looks very thin and sharp, but it winter it's a bit more rounded. I've also heard it's climbable when it's plastered, as long as the snow conditions are good.
Looking for first hand info from people who have climbed the Mönch in winter
