You are right. But he doesn't even go to Rostelecom this season, so maybe it's time to drop Finlandia at least once and try some other CS too.
Mika is a very charming young man, he will be widely welcomed I'm sure, so I think Nebelhorn is waving to him haha.
Espoo/Helsinki is half the distance compared to Moscow. And doesn't have any pressure from the Fed watching him - of course, I wouldn't be opposed to Nebelhorn or any other CS. He went to Zagreb last year, so I'd say he's not exactly opposed to changing things up. Maybe if Nebelhorn wasn't so close to Nepela?
