QST 92 ?

Hey guys, I'm looking to pick my next tree/mogul ski and could use some advice. I'm an intermediate/advanced skier, currently have one pair of skis being the Black Crow Camox 180cm, but I'm seriously considering the QST 92 after reading great things about them. For someone who's 6'0" and 170 lbs, would you recommend the 176cm or 184cm size? Also, what are your thoughts on the QST 92 overall?

Big Sky, MT is my resort. While I love my Camox skis, I'm looking to switch it up and try something different, and the QST 92s have a shape that's quite different from the Camox. On a typical day, I usually enjoy to rip a 1-2 blue runs before heading off-piste onto black diamond and double black diamond runs, with a preference for moguls and trees.
