Hmm, this is actually somewhat challenging. Flat is your best bet for the camber profile in my opinion.
If you can wait the Signal OG comes in Flat for 2013, its under $500 and great for what you want and you'll be able to keep it smaller cause its super stable, try the 155w. I weigh almost what you do and I ride the 151 everywhere.
If you don't wanna wait, look at maybe the K2 Slayblade, Lifelike, or Protohype, Ride Berzerker, or Nitro Blacklight.
why flat over the camber?
