For me, what stands out is her relaxed flow down the hill, non static movement, freedom and lack of contrived positions and "poses".
She is moving efficiently and enjoying the feeling of mastery, not trying to look a certain way to pass a test or win a form competition.
Yes, those top level instructors noodler mentions as his ideals are great skiers, but they are also trying to look a certain way, while this Kaylin is doing what works well and feels great, imo. I'm no racer, but I'd put a bet against noodler that this past olympic racer, retired female would beat his ideals down a world cup race course... ?
cheers!
