JaneB, wow you really are TINY!
I'm taller than you by 5" and proportionately more # - and I was in the same hunt last season: looking for the same ski capabilities. Here are a couple more that will likely be available as demo options:
K2 Lotta Luv
Dynastar Exclusive Legend
These were my 2 finalists after a demo day last season. Difference: the K2 is heavier and skis heavier, also has a higher preferred optimum speed. (I'm also a New England skier.)(obviously, per my screen name) Both these skis made the transition from not-deep but definitely powder to crud to hard pack very nicely. The Dynastars are so light in weight, I questioned whether they'd have the "beef" to do it all. They did. This was what I wound up buying (in a 158), due to a price-point. If the K2's had been less $, they might have been the winners. (budget, you know?
)
I will say, having been out a few days this season on the EL's, that they continue to impress me. Ski hasn't really changed in design in several years (except graphics) and could be a real nice, versatile choice for you, given your goals. (They are 75 under foot, which is narrow by many standards, but as some above stated, you may have tiny feet as well!)
Put these 2 on your list, and tons of luck in your quest!
