I've got the 2005 Murray. It's totally different than the '06.
The 'O5 is designed with one pair of fins closer to the center (more loose) and the opposite side farther out (hold's tighter). So, if you're a goofy rider like me, you'd put the wide set over your right foot and loose set over your left. Basically this helps you so when you're riding toeside you have a stronger hold.
I like the board, but I think I bought one that was too small. I'm 6'0 190lb and I've got the 138.1 bio. I'm thinking of selling it and getting a longer board. I came from a 141 Belmont - which I loved - but always thought it was a little long and thought I'd like having a shorter board.
The only place I like it is landing, I can place my landings better.
Anyway, sorry for the long answer, '06 board is different.
