Thank you all for the replies - this has been a very interesting discussion.
We have been doing a lot of research/reading. She spent almost 2 hours at Pro Fit a few nights ago being fitted for boots. Turns out that the Langes fit her feet like a glove, so she'll be getting a pair of those soon. As far as the ski goes, we went with a 2015 Head Absolut Joy in the 143 cm size (77mm waist). The reasoning behind that one is that she really doesn't think she'll be an agressive/fast skier. Once she learns, she will be happy to just make nice sweeping turns down the slopes. We think that the shorter, but slightly stiffer ski will suit her well. From everyhing I've read, both the Pure Joy and Absolut Joy are great for beginner to intermediate skiers, with the Absolut being just a tad stiffer so when she does decide to go a little faster, it should be a little more stable. Obviously we won't know until we get out there, but with the new boots, skis, and jacket she's actually a little excited about learning to ski this winter, which is all I can ask.
Thanks again for the suggestions.
