Some more great suggestions. Thanks!
Regarding size: If these were going to be Village skis mounted with alpine binders and skied with big boots I think the 180 Ruby or 176 Goat would be great. She rips (IMVHO) on her 174 Phat Luvs and would enjoy the stability of these skis.
However, the niche I am trying to fill is a bc tele ski. I'll probably mount Voile Switchbacks and she has 3 buckle T2s. She handled my 180s fine but they weren't ideal for every day bc skiing, so the idea here is not to find the biggest ski she can handle but to find the most fun ski for deep, soft snow.
Keep the ideas coming. I think the Pika might be the winner so far.
