before you get the newschoolers hater response, good judge the ski out for yourself, if you like it buy it... i asked similiar questions and they just hated on the skis. Judge for urself
u need to buy the scratch fs or the trouble maker. at ur size, those skis will handle everything and do it nicely. dont settle for the ten80 unless ur doin a lot more park than ne thing else.
04/05 1080s are a sick ski but I wouldn't suggest it if you are doing only park. Spaceframe technology gives the ski a lot of energy out of each turn (like a race ski). It is better suited if you are doing a mix of park and freeride. As for length, i'd go between a 160 and a 170.
