I wasn't clear that my purpose of posting the guide website's description of the Studlgrat was to point out how they were "glossing over" a bit. I could see how Kerstin looked at that and wanted to do it, or TP showed her something like that to say how she could do it with what they've done that year. The guide site may have bee trying to attract customers, and there may be more guide sites like that, which could lead someone to think it was ok. But if they had actually hired such a guide, they would have assessed them and their gear, and told them to go try another mountain, but not this mountain, or route, in January.
