Where are you from? You don't have to say, but it would help to know what you have available in your area (I'm guessing by the use of cm you're not from the States, which could possibly take a couple companies out of contention)
Also, we're going to need to know your weight and boot size. Weight is actually more important than height regarding the length of your snowboard.
Besides Burton, some brands to check out are Ride, k2, Nitro, Atomic, and Rome among others (top of my head list, don't shoot me
Ride has the Machete which might be up your alley. It's supposed to be a board you can take all around the mountain while still being nice in the park. Compared to this years DH2, however, it sounds like it might be the more parkesque option. The DH2 is more of a "the mountain is your park" board (from what I've heard...)
2011 Ride DH2 - Review - Ride Nation
Review on the DH2 with some talk about the difference between the DH2 and the Machete.
Rome support responded with the Agent (or Agent Rocker) for a everywhere and the park board.
k2's Darkstar is supposed to be pretty good around the mountain for a park board. Not sure if that has changed since the old models were cambered and this year's has the flatline tech.
I think the Atomic has the Hatchet? If Snowolf sees this he can talk more about it (among others).
Nitro has the Swindle which Angry liked last year. The Angry Snowboarder Blog Archive Nitro Swindle with Raiden Pushers My Take
That should give you some other options to look at till some people pipe in.
Oh yeah, NeverSummer before anyone else mentions it.
