You'll definitely want a wide board... any board that's not a wide is probably going to have you hanging WAY off the edges... (I'm an 11 and a half and I'm pretty close even with my duck stance on some boards).
I'd stay away from the Bullet, it's pretty flexible for a directional all mountain board (and to be honest, you'll outgrow it soon if not already).
The Ride Antic should be a pretty good choice (and it's in wides!
). It won't be anything amazing to be honest, but it should get the job done. The Ride Machete might be a good choice if you want to go a more park oriented route (it can still be taken on groomers, and it has a lowrize rocker so it might help out a bit on powder days) or if you'd rather focus a bit more on groomers and powder a Yukon (if you can find one) would be good. The Yukon is a Concept TMS, but in wide format.
The NeverSummer SL-R (or SL) sounds like it'd be a good fit, but it won't fit your boot size. You'll want it's wide brother, the Legacy-R. The only problem with this is that these are expensive compared to other boards at this time of year (and sometimes a hard find). While it'll be a bit stiffer than the SL, the Legacy-R should be playful enough to fuck around with in the park, stiff enough for groomers, and it has reverse camber so it'll be nice for float on powder days.
There's plenty of other choices for sure, but I'll let other people talk about it.
To be completely honest, however, most people buy at least two boards (one for freeriding (groomers/powder) and one for freestyle (park)). It's not a necessity, but it helps out a lot.
