So I've been riding for five years (this will be six) on a no-name (LTD) beginnerish board. Last year I upgraded to Rome Arsenal bindings, and this year I've decided it's time for a new pair of boots and a new board.

The info:
20 years old
5'11"
~200 pounds
Size 11 feet (maybe 10.5 for boots)
I've been riding a 156cm board

I mostly freeride, though I'm looking for something versatile as I'd like to try my hand in the park. Got a season pass to Stratton, Okemo, and Mt. Sunapee, so I plan on getting to the mountain as much as possible. I'd say I'm on the lower end of the "intermediate" spectrum - I fly down blues and occasionally ride blacks. I'm looking to spend around $400 tops on the board and no more than $150 on the boots if I can help it. What direction should I go for something that will last me a while as I (hopefully) improve to the "next level?"

For boots I've only looked at a couple
Burton Hail (2008)
Burton Freestyle (2008)

The boards I've considered are:
Rome Crail - $330
Rome Anthem,Slash/Agent - ~$500 is pricey, but you never know
Ride Fleetwood - can get a 2008 155cm for $179 after 50% off (too wide?)
GNU CHB MTX - $400
Burton Custom '08 - ~$350-400
Burton Clash - $300

Any other suggestions I might be missing?
What size should I get?
What width board should I look for?
I know Burton uses a different hole pattern for the bindings - this means I'll probably have to butcher my brand-new board to get my Rome bindings on, right?

Thanks for reading/listening/helping!

And for chrissakes, START SNOWING!
