Replying to Remedy 102. Where to mount?

This is her first freeride/powder ski.

She is a solid intermediate and 5'9" ~140 pounds so went with the 163 length as opposed to the 170. Now we have to decide where to mount. I was thinking around +2 from traditional. I don't want to go too far forward since she already went to the smaller size ski. At the same time, I have heard that the shreditor skis best at near-centre mounts, and doesn't have enough strength in the tail to mount at traditional.

Where would you mount the remedy 102 for an intermediate, mostly directional skier? By intermediate I mean skiing double blacks comfortably, but not necessarily charging anything. Less carving and more sliding on the steeper stuff.
