I recently demoed a pair of Rossignol Experience 82 Basalt (and the 82 Ti, as well). The 82 Basalt ski is the absolute easiest ski I have ever been on to carve on almost any terrain. It works at 5 MPH or 35 MPH, easy short turns, easy long turns, easy GS turns. You don't even have to think about this ski .... just tip it and it turns and doesn't punish you for mistakes, which I make A LOT of!
I am a low intermediate and quite a bit bigger than you. The 176cm was great for me and held my weight (240 lbs) surprisingly well. The ski is also no problem in afternoon chop and/or slush. Easy, easy, easy but with a high performance threshold, I hit 40 MPH on icy slopes with this ski a couple of times and it was smooth as silk. At your weight, it would be even smoother!
The Experience 82 Ti is even nicer. A bit less forgiving, perhaps, but still not a terribly demanding ski. It turns well at low speeds and I am not good enough to find its speed limit. Same turning characteristics as the Basalt ski, just more damp and even more stable. If I didn't already own the 86 Ti, I would buy this ski. If I were under 200 lbs, I'd buy the Basalt.
I realize these aren't the "true carving" ski you mentioned in the OP, but they are fantastic carvers that help you progress and offer versatility while also being user-friendly and a bit more versatile than dedicated skinny planks.
