How strong of a skier are you?
Are there parts of Europe your frequent more than others?
I think something in the 98 to 108 range underfoot is good for an all-around, on/off piste ski-- at least where I ski in the Austria/Swiss Alps-- if you can't pick your days. Last year I used my Bonafides in everything from hard pack, to crust, to waist-deep and light. Mostly off-piste, but perhaps 20% on. They excelled at everything on piste, and were great off-piste. They just didn't feel super fun going very slow.
My buddy was on Mantras the year before, and then switched to Cochise. As a single all-around ski in the Alps, I think the Cochise was an even better idea than my Bones. Perhaps a little easier to pivot in the trees, and a little easier to get to release the tail. But no speed limit and a crud eater.
This year I picked up a Rocker2, and after the first 3 days of the season that's all I've been on (though I did miss most of the spring), though more like 95% off piste and touring, and I could mostly pick my days. Great ski for someone light for what I do. But it doesn't eat crud like the Bones/Cochise, and it can be made to chatter on icy hardpac
Depending on your skiing style and other factors, some ideas:
- Rocker2 108 (more playful)
- TST (more playful)
- DPS 99
