My estimate was pretty much bang on. The 190s are good for her. I think, looking at your weight, the 180s would be a reasonable choice... but the 190s would be faster. You're a good 10kg WITH gear below the recommended weight for the 190s, right?
Probably not an issue for you @beeeweee (although I do understand ski-chosing anxiety better than anyone, oh my god), but if you're on the cusp of these skis in weight without gear, I'd recommend getting the longer ones. This was my experience, anyway. I really loved my 190s! But I would have been better off with the 200s for what I wanted to do, especially with skins on the waxable bases. These skis are made for cruising and fun 'shortcuts' (heh) home off the trails rather than, say, climbing high in deeper snow. So I'd maximize the whizz by choosing the longer ones. Whizz is their raison d'être.
They're a LOT of fun coming down in good conditions, maybe a little hair-raising if the conditions aren't perfect or you ski 'comme les danois', but so nimble, tapdancing shoes. They can smash miles and miles in the right conditions. They really work as fjellski on surprisingly deep snow, albeit their true element is a few inches of fresh snow on consolidated snow. That's where they shine. I mean, maybe there are better choices for the wilds, but it's worth bearing in mind that MR48s/ Holmenkollen have been to the North and South Pole, so they're the real deal. For a combination of trails, shortcuts, tracks back to the car, these are so great.
