I absolutely love my anthems. They're nice and soft and super playful. Really get great for rails and still hold up fine on smaller jumps. I've had tons of fun on mine and I'm sure you will too.
However, since she's a girl (no sexism intended) she's very likely lighter and smaller, and the softer flex, while still not being amazing on bigger jumps, will work pretty decent, better than they would for a guy on the same skis.
