Replying to Fellow newschoolers! i need some binding help!

so i got some skis for my girlfriend cuz she wants to switch back from snowboarding (score). shes about 115-120 pounds i think.. and she wants to ski all mountain and some park. i found a great deal on some salomon z10 bindings, i was wondering if those would hold up or not, if she would pop out a ton for no reason, or if i should just step up from 10's to 12's. any input from someone around the same size and din10 range bandings would be a lot of help! and +K FOR ANYONE THAT HELPS.
