hey i have been looking to get some new powder skis and keep coming back to the k2 hell bent does any1 no how good they are?

i am about 5' 5" or so and wondering what size of a powder ski i should get. should i go longer or what:P

I know one guy that loves them, calls them 'cheating' on powder days. Then again, he is an awesome skier, and says they are useless on groomers. So unless you are a really good skier, and get to ski a lot of powder....
