Help With Picking Out A Board Please

Well I'm into freestyle now and can 360,almost all grabs, and some grinds but my board I think is holding me back. I have an old Burton board that is extremely stiff. I've been looking at the K2 WWW, or Rome Graft. I know there are a lot of other boards out there but these are two I've heard good reviews on and don't cost that much. I am 50% jumps(35 foot at biggest) , 25% rails, and 25% freeride. What one of these boards will be best for this. And also suggest boards you've had good experiences on that might fit that category. This board will probably be for next year and planning on getting it at the end of this year. I'm 12, 4'10", and 85 pounds but his is for next year.
Thanks to anyone that answers

At that size you're pretty limited. You might actually look into some girls boards that have some more nuetral graphics. They'll better suit you. The K2 VVV is the girl version of the WWW, try that. Stepchild Slim is another high recommendation for ya. Look for someting no bigger than a 144. Even that small will let you grow into it. Really for your size I'd say maybe a 140 but you'll grow out of that in a season. I know at twelve you may have some reservations about getting a girl board, but just plaster it with stickers and if you just ride like you don't care your riding a girl board, noone will care. And if anyone does, their opinion probably doesn't matter anyway.

SO...
K2 VVV
K2 Fling
Stepchild Slim
and for Grom boards
Nitro, Burton, or Flow.
