Replying to Shreditor 112 length opinion

Sup guys. I'm a 6'2" guy, 170 pounds and looking to buy the 2015 K2 Shreditor 112. I'm an advanced skier that likes to charge on groomers and moguls, but appreciate to take it more relax on those rares powder days we've got on the east coast.

So, here's the dilemma : pick up the 179cm or the 189cm? Basically, I already have a good pair of skis that I use most of the time, and was looking for a playfull powder ski that I can maneuver through tight trees, hit some cliffs and stuff like that.

With all that in mind, i'm leaning toward the 179cm, which I know is short (I ski on a 184cm ski normaly), but is it too short? I'm just afraid de 189cm will be too cumbersome for what I want to do with those skis. On the other hand, will I have enough flotation on the 179cm to have fun in deep snow?

Let me know what you think!
Thanks a bunch
