I'm probably not really qualified to make recommendations, but my True Luvs (K2) have served me well for a couple of years now. When I bought them, I was told they're "all mountain" skis, but they're more comfortable to ski on groomed runs.
I'm also 5'4, still heavier than you, (160 now) and ski them in a 153. I've been primarily skiing groomed blue runs for quite some time, with the occasional easier black run. Not much off trail skiing for me. What you've described sounds similar, so perhaps my experience will be a little bit helpful?
This year I've been moving off trail more than ever before, and I have to admit, they're not as much fun as the Lotta Luvs I tried out a few weeks ago when the snow's not so "neat." I think the wider, heavier Lotta is probably more realisticly an "all mountain" ski. The True Luvs are okay on groomed runs with a few inches of powder on top, but when that powder gets pushed around a bit, they don't like that as well. I get tossed around quite a bit because they don't want to go through that stuff.
That sounds kind of like I don't like them anymore, doesn't it? But that's not exactly true either! Sunday, I had them out again on snow that's been through a week or so of warm weather, so it's been packing down, freezing, that sort of thing. We stuck to groomed runs, and they and I were delighted with the well-packed with groomed stuff on top, snow conditions. (they do need a tune up again, poor things, but still performed well)
I was telling DH that I thought it would have been a good day to do another Lotta Luv demo --- I tried those while at a resort over MLK weekend, and we had like 30" of powder land while we were there. I loved them in that and on the pushed around crud stuff there. Once I got used to skiing on them, I loved them on easy groomed runs too -- the snow was still pretty soft under them. The first couple of runs they felt pretty fast and a little bit scary, but that often happens to me right after lunch when I sit down for just long enough for my body to think I must be done (silly body!)
I do want to try the Lotta on "our" snow too, particularly on the crusty snow. I figure it's more important to know how I like skiing on them where I ski normally than how they do for me when I'm on one of those relatively rare excursions to anywhere else! (riding up on the lift, some people visiting from Massachusetts said that we had what they're used to calling "good snow" on Sunday, if that means anything to anyone. Here it's pretty solid stuff, nowhere near as much fun to fall on as the last few weeks of falling have been!)
I don't know if this info has been any help at all, but maybe?
