Thank you all for the feedback and info! Very helpful! I'll interject here briefly to make sure we're all on the same page. The skis I'm looking for won't be a daily driver, but rather the upper end of a 2 ski quiver, to be used when we get enough snow that her everyday skis (70-75 mm at the waist) become difficult and the wider skis represent a more fun option. (Realistically, I'm guessing 30% usage.) As for her "physically", she seems to be following the pattern that her Mom and I exhibited, as we are both bigger, taller, and stronger than average and we both matured early. While 90# and 5'0" now, I'm guessing she'll be 5'2" and 110# next season and 5'5" and 120# the following (and may exceed those numbers since her feet just outgrew her Mom's).
I'm not at all stuck on adult skis, but it's a lot easier to get details and skiing characteristics on the adult skis than it is the juniors so I gravitated that way, particularly knowing that within a year she probably fits the bottom end of the size/weight demographic that the shorter women's skis are intended for. Line's Sick Day Shorty is a junior ski that has piqued my interest, but I'm not sure how that in a 152 would differ on her regarding wear, tear, and fatigue than a soft-flexing women's ski in the same (or shorter) length?
