Go ahead and get the Lizzies, they'll most likely ski you though...if I were choosing a fat ski for a smaller rider, I'd look at these:
K2: The Seth 169, Nancy 159.
Line: Chronic Blend 165, Anthem 161, Celebrity 158.
Armada: ARV 165.
4FRNT: MSP 160.
Liberty: G-Note 163
Volkl: Aura 156 and 163, Karma 169.
I'm sure there are also other skis out there that would work for you, and don't think that just because some of those skis are made for women that you shouldn't consider them, remember that they make womens skis for lighter riders, and you're pretty damn light...don't go getting a ski that'll run your ass into the ground just cause you think it's a cool ski...like the Lizzie for example...it's an amazing ski, but it's not the right ski for you at this time, therefore, if you were to get it, it might look cool, but you probably would not be able to handle it, simply because you are small and it would be way to much ski for you. I'm not saying you're a bad skier either, but the best way to get hurt is to ski outside of your abilities, or to have a ski that is outside your abilities...give it time, Lizzies will still be around a couple years down the road, and you'll have way more fun on them when they are the right size ski for you. Peace.
