Replying to Night Trains vs Mr. Pollard's Opus (for a girl)

So, I know this topic is on here a million times, but most threads are for bigger guys.  I'm a lady skier, 5'9 120 lbs and I just want to make sure these skis aren't an overkill for me...  Right now I own an old pair of surface live lifes and armada ARGs.  I'm looking for a replacement for my live lifes that is more powder and jib orientated.  About my skiing style:  live in SLC so I ski regularly, love to hit smaller cliffs (5-15 ft), obviously love powder, no park, short touring trips around LCC and BCC.  I'd probably put a touring set up on the ski...  I know the night train is a stiffer, more stable and the opus is softer, maybe more playful.  Any lady skiers have experience with either of these skis?  Any other suggestions for skis I should consider?

Also, anyone know of places in SLC/park city area with moment demos??  I can't seem to find a demo shop that carries the night train...

Thanks!
