Yes it is, maybe with the exception of St. Moritz. What alos sucks is that cars are not allowed in the village. Doesn't matter for you americans but it sux if you travel there by car.
Easiest and cheapest way to get there would be by train and Bus. From Zurich it's about 1 1/2 hours by train and then about 40 minutes by bus. For train and bus timetables you can check http://www.sbb.ch/en/index.htm
Last year they had an online registration (which is not up yet) in place...
I tried the Snake BC (the yellow one) this summer. Pretty nice ski, really soft and forgiving compared to my mad_trix. I only did a few laps in the park, so i dont know how they handle on groomers or pow.
voelkl karma maybe. they're long enough and not to wide to ski park/pipe. And as far my expirences with voelkl go, they're durable and make a good all-round ski too.
or maybe a head mojo 90. i think they are more or less in they same class as the karma and also very durable.
