He is right. If you arent going to be 100% in the park, look at a more all mtn oriented ski.
100% Park
T-Hall
Fujative
Invader
70% Park
Ar5/Ar6 (whatver is cheaper)
Thruster
Scracth FS
Troubly maker
50% Park
Public Enemy
Leep in mind, you dont need to get THIS YEARS skis. I almost always buy  a season behind...Like this year i have 05/06 T-halls. I do this for a few reasons....
1 Much cheaper
2 The ski has a season to prove its self (Invaders...everyone bought them, and tons of problems)
