Yet another "What size ski should I get?" Thread

ok so i'm thinking about getting new skis mid-season (when i save enough money)...I'm 5'5 (expecting to grow) and hope this is the last pair of skis i buy for awhile (I'm a junior in high school, plan on skiing next year but i dont know about college because of where i want to go, if im gonna work, etc)...anyways, i want to get 175 ARV's, would they be good to grow into? thanks for the help and sorry i gave you my whole life background lol
