If all you do is ski park and don't hit big jumps, the afterbangs would probably be a great ski for you. The invaders would also be a good choice. If you plan on skiing outside the park, you might consider the Armada ar6. For future reference, this should go in the gear talk forum. You also might find some useful information by searching too.
yea sam, id say u dont need the afterbangs specifically, not that theyre not a great ski but for buck u dont need anything special any centermounted ski will do for you.....i think i have a pair of "broken in" 08 JO pros in 169 that id prbly be willing to part with if u need a cheap pair....though i think your mom wouldnt like the topsheet
