Started with a 144 Parks this year and exchanged it out for the 143 3DS. Great board, carves insane, and the pop on the wake is controlable. Every time you hit, it is like the time before.
My Parks never let me get comfortable with the "hit" off the wake.
I'm 6'1, 200lbs and the board feels great! I don't think that I would go any smaller than that. It's nice to have an aircraft carrier to float on.
Go for the board, you won't be disappointed.
