Replying to Moment pb&j WHAT SIZE?

Hey I've made my decision, I want the pbj's. I'm 5'7 125-130 lbs still growing, probably will never hit 6 feet likely height: 5'10. What size pb&j should I get, they come in 172 and 182 cm I want them to last me for at least 2-3 years, but don't want this upcoming ski season to be crap because my skis are to big. Which ones? I want to be able ski some park, but rip groomers, trees, and moderate pow. I will probably be 70% groomer/park, 30% powder. Any response helps thanks!
