Last season I put up a post on my blog about some Interski runs by demonstrators. The point of the article was to demonstrate the movement differences based on alignment; less on technique or national preference for skiing. I posted it, it has Reilly and Paul in the group with an Austrian and an American.
I posted the link to Facebook, so the post has been there around for a year. I know many of you are not on Facebook; however if you can access my page you can have a look at the posts. I have recently received two posts from an Irish instructor. After you read the posts you will understand why I have such a low opinion of Interski, instructor understanding of skiing, their ability to present skiing and teaching.
Another example is the Canadian, a strong, athletic, guy, Beaulieu. His presentations are a mess and his understanding of skiing is horrid, but he's a good skier. So being a good skier doesn't mean you can teach, understand or present skiing. This is true even on the world cup, and with ex-world cup racers who turn to coaching.
This is the link to the discussion, it is a long thread with many good posts. But there is also lots of filler. https://www.facebook.com/hrharb/posts/10206984754873291?comment_id=10209994574596903¬if_t=comment_mention¬if_id=1476883951073459
