In reply to John Cuthbert:
I was actually looking at Blizzard skis, originally (The "Rustler 10"s, when I was doing my research at the beginning of 2018, although I see that there's a new 90mm one called the "Rustler 9" that might make more sense for me, now.) but, after careful consideration, I decided that I didn't actually want a "one ski quiver" because nothing sucks like lift queues.
I might wish I was always in the back country, well away from crowds, lifts and après-ski (the latter also known as "hell", to me) but I'll still probably end up in-bounds for at least two weeks every season simply because that's where our friends, family and enemies mostly are. There's no way I'd want to have fragile, light-weight touring kit on the ground in a popular venue in the week of the Dutch holidays, for example (nobody ever learns to check the European holiday calendars before booking, do they?) -- even if the skis survived without a scratch, I'd certainly worry about them constantly.
I decided to buy some new-ish rental skis for in-bounds skiing after my last week of that -- a pair of HEAD V-Shape V6's is what ended up dripping snow all over my car -- and went looking for dedicated touring kit exclusively for use on tour, apart from a bit of a test run and DAV courses that sometimes use lifts.
I'm perfectly happy with these Dynafit not-a-clue-what-model-they-are 90mm jobs. I can ride them on a piste even if they're twitchy and I didn't buy them for pistes, anyway.
I tried an ascent next to a piste with them and it was a mind-blowing experience. I had never gone "up" on skis, before, and was a bit worried that it looked like a proper pain in the arse. After giving it a go, I can honestly say that it didn't feel any more difficult than walking up a zig-zag path in the summer. (Of course, coming from Cape Town, I am well adapted to steep, mountain "stairways" and generally prefer that sort of thing to slow, rolling hills or moderate climbs. This fact may or may not be relevant.)
The most difficulty I experienced was caused by the fact that I had the wrong baskets on my poles and couldn't use them for lateral stability because the snow I was testing in was so soft -- I felt like I was about to perform a slow topple to the side at any moment.
