In reply to BARNEYHIGHROPES:
Tony Howard's guidebook is incredibly detailed - the Troll Wall section alone covers no less 13 pages, with 7 diagrams and 7 major routes – from left to right on the face: The Norwegian Route, The Arch Wall, The French Direct Route, The Escape Traverse, The French Direct – Polish Variant, The Rimmon (English) Route, and The Swedish (Trollgubben) Route. It also mentions two Russian routes, and another British attempt. Here is just one of the 7 diagrams. I just cannot understand how you don't consider this guidebook essential for your purposes.
PS. There's also a Russian Climb, and several useful diagrams that can be found on the internet of it and other adjoining routes:
