Burton Custom is far from a generic board. Lots of them sold for sure, but many people have no business being on one or a Custom is the wrong board for them - however for you it actually sounds pretty much spot on. Definitely consider/check out the Custom (regular camber version, not the Flying V and probably not the Custom X either).
I think what bobby's saying is that a lot of people have them. No doubt it's a rad board though. I know what you mean about people buying the wrong board. I see a lot of people on custom X's that can't make turns.
Bobby, if you wanna get REALLY boutique, and still have fun in the park I'd check for a flat board from these companies.
Dinosaurs Will Die - Try the Genovese
Amazing company that's also owned by riders.

Smokin LANE KNAACK - I'm having a hard time finding their website, that sucks, they're an awesome company who make their boards here and riders get a cut if you buy their pro model.
Smokin, I believe, uses magnatraction on all models, that could come in handy on the east coast.
If these are hard to find, I'd go capita outdoor living or midlife zero depending on your boot size.
Or a Signal, they make a flat I heard is dope.
[FULL DISCLOSURE: I have not ridden a flat camber board, but was interested in one for the same rider purposes you're looking for. The people I know who ride flat, are stoked on theirs. Just spreading the info...Good luck]
