I am 6'3 185. when doing Iaps of Golden Eagle and Ripsaw@ Beaver Creek all day, which has pretty variable conditions i usually ski Line Blend 183 or Nordica Patron 193. The 113mm patron carve well for a semi-fat ski but on variable conditions, still the 100mm blend is MUCH MUCH better. that being said, the nordica patron is MUCH MUCH better than my other pow skis ( K2 obsethed 189, Surface New Life 194) on variable.
The blends, however, are less stable for drops/cliffs.
I would say for one ski that can handle some deeper pow and cliffs, and still rip on hard or variable conditions rather well, go with the Nordica Patron. They can handle the deep and 20 foot cliffs. if thats what your into.
If your core, go with Moment Governor/Special 196 or Moment Belafonte 187/192. They can handle Legit anything you could think of.. very stif tho, almost planky.
