She sure is! Unless you're one of those fools who considers that there is more to being the best than just performing switch spins and hitting rails.
You know, if you're like, one of those idiots who considers things like, halfpipe, powder, and plain old overall skiing skills to be an important part of skiing.
Not to take anything away from Kaya, she is absolutely awesome at what she does, and no doubt will continue improving rapidly because she has incredible talent and apparently zero fear... However, she still has a ways to go before becoming a truly well rounded skier like Sarah, Michelle, Grete, etc. Claiming that she is "BY FAR" better than skiers like them, is just not true.
