I ski with the "other side" every now and then. The clear message I get is that all the movements that we consider absolutely wrong they consider right - and they see no problem with those movements. They continually point out that they can ski "just fine" with their movements. They don't seem to be concerned about using more efficient movements and they aren't concerned about the kinetic chain, but they do think that they ski biomechanically correct because they say "quite frankly if it weren't correct they wouldn't be able to ski". I quit the "crusade" with these types a long time ago.
When it gets right down to it I looked at Harald's skiing and the skiing of others and decided I liked Harald's skiing best. Believe it or not there are some people out there that actually profess to not like Harald's style of skiing. Personally I think they're really just trying to justify their own poor skiing movements.
