Replying to Line Chronic Help

hey guys im thinking of buying the 2011 line chronic in a 163. im like 5'2 and a half and about 120lbs. (im a pretty small kid for my age) i was just wondering if the ski would be a good choice for me, im gunna ride about 80% park 20% everything else. im trying to figure out whether it is too stiff or too heavy for me. i had the a bangs last year and i found that they were a pretty heavy. if i missed anything let me know. +k to anyone that helps out.
