I skied the 7.6's for a season as well. If she's a HS racer, I'd assume she's a very good skier.
For out West I agree with Kevin that she would be better off on something wider. You don't need to go to a powder ski, but for Western groomers an 80-85mm waist would be a better minimum width and still a great all mountain ski in the east.
I skied the Magnum 8.0 ca's this year and loved them, a little longer turn radius, more stability in crud and chopped up snow, and no loss of carving ability. The woman's version of that is the Viva 8.0. If you like the Magnums this is the closest and a bit wider - 80mm underfoot and a little more substantial.
The women's 7.6 is the Viva 7.6. My wife has those and is very happy with them, even in the West. So I don't think it would be bad to go with the 7.6's if much cheaper or available to you.
Lots of great skis out there in that waist width.
