Interesting about the ski length. I'm 6'3" and ski 178 cm supercross skis. I love them, and frankly, I ski as much backwards or on one foot as I do facing downhill. They work great for me.
I've just been reading up about all this camber and rocker stuff. I didn't even realize there was that much difference. I'm thinking a front edge rocker, with a mid camber, and a flat tail would yield good turn ability, with good straight line ability for a beginner/intermediate person.
(BTW wife is 5'10", not 5'11")
I'm 5'5 190 lbs (not a typo), female, and my everyday ski is the Line Sick Day 110 at 172cm. There's a lot of rocker in it.
Honestly the only way to really know what skis you like is to have experience on different types of skis. Practically speaking, that means to demo. The other option is just to buy something and learn to ski it, as you seem to have. Your ski seems super short to me for your height and weight, but if you're having fun ...
