Libs are priced pretty high. Worth it? I guess that is in the eye of the beholder. Some would say yes, and some would say hell no. I bought the 2011 TRice for $350 brand new so I felt great about that price, but not full retail.
The TRice is a great board, but like the last reply says, it isn't a park board but more of an aggressive all mountain board.
What do you plan on doing in the park? If you are just hitting kickers than the TRice might be a great choice. If you are doing butters and rails, not so much. It's pretty stiff.
