Replying to Armada ARV 106 vs 116

so I'm going to Japan in January until late Feb which is basically when there is heaps of pow pow.

Currently I only have a pair of Line Chronics which I use as my park/all-mtn ski however I need a ski that can handle the deepest pow days in Japan but also hold it's own on groomers as well as a few park laps.

The fattest ski I've skied is 96 underfoot so I'm kinda torn between going with 116 or 106. Plus the 116 has the 3D tip which the 106 doesn't. Which ski do u reckon is better suited to my needs?

Thanks everyone
