In reply to Gazleah:
The Swedish route is some 25 pithes route up the Troll Wall. And you can add 4-5 pitches for the intro slabs. Grade Norwegian 7, equal to american 5.11 or British E2 - E4 (should get a high E in this setting). It has been done in a day, but most parties uses two to three days.
BUT, the Troll Wall is falling apart. Well, all mountains does, but this one faster than most. For the last 20 years there has been major rock falls nearly each year. The largest happend in 1998, when the Rimmon route lost 5 pitches (actually they were replaced by 5 new pitches). The rockfall measured 2,05 on the Richter scale.
The Rimmon route shares some pitches with the Swedish route, but the rock fall didn't take the Swedish route, but was very close. Lots of loose rocks and debris was spread on the lower parts of the Swedish route and on the intro slabs.
Two Swedes did the Swedish route in three days in August 2002. They thought the 12. pitch was destroyed by the landslide in '98. The new pitch was both loose and very difficult. NB The route was repeated again a few Germans in 2003. They believed every pitch above The Terrace was intact (including the 12.) It was the two pitches under the Terrace that had most signs of the slide, but none were destroyed.
While you can climb all through all night in June in Romsdal, the end of September has shorter days, and a high chance of bad weather. The rockfalls appears mostly when it rains, and the wall is not a pleasant place to be even if you don't get hit by the stones.
British climber Michael Garton tried the Swedish route solo in the summer of 2006, and on the lower part of the route a ledge just disappeared beneath him. He took a huge fall, and got injured. By luck he got rescued with a helicopter from the Norwegian Rescue Patrol, but all his stuff is still hanging up there, as no one has been there since. And I don't think you should go there either.
