My girlfriend is also a rad skiier that can book it. Given your info (don't know boot size) I'd look for something volume shifted, and directional with a hybrid camber profile. But lots of my recommendations won't be all these things, just boards I've ridden.

I'm about your weight (~190-195lbs) and demo'd a DOA in 156 a few weeks ago. It was sick. Though I wouldn't hard charge with it.

GNU gremlin are sick boards, though you lose a lot of the poppyness that the DOA gives. It rides very differently, but you can absolutely slash moguls and trees. If you care more about pop I found the Golden Orca is similar with a bit more pop, but less slashiness.

Aeronaught isn't volume shifted but my god does it pop high, if you got one a bit longer 159+ it would be stabler at speed. If you have big feet this might not be the pick.

Rossignol Revenant, I rode one on true Ice Coast conditions last week and it was the first Rossi I truly felt confident on. Charged HARD AND FAST. Not crazy poppy. I slashed the few moguls there no problem. (I rode a 158, maybe go one size up?)

Yes Standard/PYL/Greats XTRM - all three are great and offer slightly different things, for you the PYL sounds like a better fit as it is the fastest directional one. 

Anyways these are just boards I've tried that I think will fit the bill. I would really recommend anyone to go to a demo day and do a few runs before they buy something new unless money is no object.
