I am 170lbs and 6'4". I ski mostly blacks/doubles and am looking for a good all around ski that I can take all over the mountain. I have narrowed it down to the following skis, based on my budget and current availability. All are demos being sold, except for the Atomic Theory's which I would buy new (they are all comprably priced). First off, is there any major problem buying demo skis, I don't have a ton of money to spend on nice new skis. Second and most importantly, which of the following skis are best and how should I pick between them. Let me know if there is more info I should post about how/what I ski. Thanks for the help!
