Good snowboard for park?

Well first of all, how tall are you? A 162 for park is a pretty huge board. I'm 6' 1" and I ride a 155 for rails, 158 for park. You need to decide if you are going to hit more of rails, boxes and small jumps, for which you would want a smaller more flexible reverse camber (rocker) board, or if you are going to hit bigger jumps and bigger rails, which you would want a tad longer and a tad stiffer overall. Also keep it cambered (no rocker). For the first option, I would go with something like a k2 WWW, rome artifact, or Automaton manimal. All boards I have ridden and are great. For the second option I would go with a Rome Agent, K2 darkstar or Automaton Mixed signals. If you are kind of stuck between the two options, the K2 parkstar and Rome Agent rocker are both excellent boards that are a tad stiffer but have reverse camber for locking in those presses. I have ridden all of these boards except the Agent rocker and K2 darkstar and they are all wonderful boards.
