o.k. so i was wondering if this is a good twin tip ski to start twin tip sking. i've skied before and im very comfortable on greens and blues and im starting to get into blacks. im 6ft 240lbs and i was looking into the 179cm ski. note this is for the 04-05 model and i know they changed there dimensions after this model but i was wondering if i can get a new pair cheap if its worth it? i mostly like groomers but i wanted to try twin tip this year and i've heard good things on PEs being a good all around ski. so let me know what ya guys think about this ski. Thanks!
