Interesting thing about the Austrians is that I have seen video of several guys from their demo team skiing totally different when not "demoing" for their system... more-so than in other systems. Quite a few of those guys have some very unique talent. They do have that weird elbows thing though. Not sure what's up with that.
I think if one were to combine the top Koreans and the top Canadians you'd have an impressive system/skier.
Worked with one of the Austrian team this winter, he could really ski however he wanted, really one of the best skiers I know, the Austrian upper body style is pretty stiff though.
I'm sorry but the Japanese skiing kinda looks like what you do as a kid, running around with your arms out and pretending you're an airplane. Makes me tired just looking at it. Not my thing, sorry. Maybe cuz I'm a Canuck and I'm also enthralled by the CSIA stuff; that's what I aspire to.....more compact, powerful, one leading to the next with some punch lurking just below the surface. French is very fluid though, nice.
To each their own. Whatever keeps you safe and having fun!
