Burton Custom X vs. Custom?

OK i know i posted a similar question to this but i just cant decide. I want a board that is Good for mellow runs through the parks. Just like getting some Air off jumps and throwing in some grabs. But i also want a board that is good for Carrying decent speeds when im freeriding. Which one would be better for me. I generally freeride more then i Freestyle but i still like to do them both. Also i see the Custom X is pretty stiff. Feel 7. Will i be able to maneuver this board at lower speeds? Also can the custom handle High decent speeds when freeriding or is this just a slow *** board?
