there are actually a bunch of boards that fit the bill for ya, both regular and hybrid camber. Regular camber will carve and haul ass better than anything out there. most of the hybrid cambers are still a little loose but i dont mind it generally.
even though your garage rocker sucks when bombing groomers, it will be good in pow.
boards to look at
Rossignol Angus amptek-gets good reviews from everyone who rides it, has a good hybrid camber, has magnetraction and a cool graphic, its good for all types of ridning-$400 new. not many people take rossignol seriously, they make really well designed boards for not a lot of money.
Ride Antic, Pretty much a little cheaper version of the machete, this board should be awesome, flat in the middle with a little rocker at the ends.$400 new
K2 Lifelike-Flat camber, behaves somewhere in between a hybrid and regular. $400 new
Capita Normal Ass Snowboard- regular camber, this thing is actually a really good snowboard for dirt cheap. $380 new
If you can swing a little extra cash the Arbor blacklist/westmark are freakin awesome decks, magic carpet awesome -$420 new
Ive seen last years Ride antic online for about $270 so if you can find that go for it.
