so im guessing your not going to be doing hardcore backcountry so id go with a nice park ski
the township is a urban/park ski, would probably be a start although it is more for urbans than mountain park im sure you would be fine riding them.

line also has some sick light skis that shreddd in the park. my friend last year got some invaders and they actually got him really good at park, take a look at the 155 line afterbangs

if you dont like either of those, what else are you more specifically interested in
