Replying to Just when I thought I didn't need help with this stuff....183 Bent Chet's OR 175 JJ's

Alright folks it look's like I'm finally moving away from the icy east coast and spending a season in beautiful Banff. To celebrate this decision I went ahead and impulse bought some 183 2012 Bent Chetler's. Having never owned a ski with rocker when I received them I got a little (a lot) intimidated by their size, so I went ahead and impulse bought some 175 2013 JJ's. But upon receiving the JJ's they seemed a wee bit short...great.

Now I have two pairs of ski's, one that seems a little large, and one that seem's a little small.

Help me decide plz.

Height: 5'5"

Weight: 145lbs-150lbs depending on how big my morning poop is

Ability: Advanced-Expert is what I like to tell myself

Current Ski: 171cm 2012 Rossi S5 (full camber)

Intended Use:
-Definitely using them as pow stick's but would also like the versatility of being able to take them on groomers.
-Love ducking into the tree's, hitting pillows, hucking cliffs and busting airs.
-Love to charge and go fast.
-Probably won't be doing any backcountry this year but maybe some side country.

I'm going to have my S5's with me for whenever theres a snowfall drought or for hitting the park so my new ski isn't going to be a one ski quiver but I also don't want it to be incapable of ripping the entire mountain.
