is the 159 necessarily long?
It depends on your riding style:
I say a 155 is your pick. I prefer rails and low speed stuff.
My friend says 159 will be good for you. He likes his powder.
For 30'+ jumps, go for the 159. The 155 will probably buckle when landing in the back seat.
Note: I see the 155 is out of stock. Other similar boards would be Capita Stairmaster, Burton Custom (this has setback), K2 Parkstar. They all offer about the same stiffness, pop and rocker profile.
