DoubleFeatureThat's what I figured for length as well. What about actual skis? Got any suggestions?
would be my pick. It's just the women's version of the shredditor line up. I would go with the 163 unless she's absolutely certain she wants tiny skis, remember the rocker will make them ski short.
K2 makes really damp, heavy (not easily pushed off course) predictable skis. They are also crazy durable, I put 150+ days on my recoils (same ski just the mens version) and they looked brand new still, just lost their pop. I feel like they are great skis for bridging the gap from an intermediate skier over to a more advanced-expert skier. They also meet all the criteria in the blister gear beginners guide to buying skis: http://blistergearreview.com/recommended/skiing-101-the-best-skis-for-beginners.
I know she's not a beginner, but that article is really just a general argument for why those specs in particular make for a good single quiver ski at any ability level.
