@Olesya C , I am definitely not an advanced skier, so take it with a grain of salt. But I am about your size. The Foundation 94 and 95 @185 cm (different year models) didn't feel heavy to me, not at all. For what you are looking for, which is a playful ski with decent float, with carving capabilities but primarily easy to pivot around, these could be money. They seem to check all boxes. They felt pretty damp in choppy snow. I would probably go one size shorter for what you want. And perhpahs 87 instead of 94, like you are thinking, will make them more versatile. In comparison, like
@James said above, the Z90 is more of a carver. Also smoother, IMHO. But it might lock you into a turn in places where you want to opt out and pivot. Not unforgiving, but it is a wide carver.
