Replying to line mike nicks

i was wonderin if this is a good ski for me (or at all). I live in LA and dont get to ski as much as id like, but i make trips to mammoth, tahoe and other places a couple times a year at least and im getting tired of rental equipment. im a pretty good skier and like riding the parks and just freeriding the whole mountain. so im curious to know if this can be used for the whole mountain or if it should just stay in the park. also what about the size, its 171 and im about 5'9'' and 140 pounds, i usually ski around a 159-165 but i'll probably (hopefully) eventually gain some weight. any help is appreciated, thanks (also other reccomendations are welcome)
