In reply to Dave: FORGET ABOUT IT!!!
After the first major rockfall the thing has been slowly crumbling. Only the left edge of the main wall is climbable at the mo. Local hotshots tried teh Rimmond and the Swedish, as well as further right to Död at Alla, everything was tottering.
If you want Norwegian big walls, go to Kjerag near Stavanger, it is way nicer rock, and 900m of vertical is enough (The Troll is 1300m at it highest I think)
