Good advice.

I'd like to have, apart from my skating skis, a pair of
skis that can be used relatively well in either a track or off-piste.

If you're planning to do a lot of your skiing within a couple of hours drive
from Lausanne, Switzerland, I'd recommend getting a pair of light Alpine
Touring or "randonnee" skis and bindings.

Telemark bindings? My experience in the Alps around Lausanne is that those
are used mainly by lift-served downhill skiers who've gotten bored or need
to find some new move to show off for people watching them from the lifts. I
see them only rarely out on ski tours.

A light AT boot (like the Scarpa F1), with a light AT binding (like the
Dynafit Tourlite Tech) mounted on a light AT ski (various models, I've got
Atomic Tourcap Guide), is significantly lighter than almost any "telemark"
setup that would be appropriate for around Lausanne, Switzerland. The Scarpa
F1 has a more flexible sole for "classic" striding than lots of telemark
boots.

On the other hand, if most of your skiing is going to be on holidays to
Norway, then listen to the Norwegians.

Actually for around Lausanne I would recommend accepting another kg in boot
weight and getting a 3-buckle boot for better control. Now you may say you
don't care about steeper downhill slopes, but once you see what range of
tours gets opened up and the range of partners who will accept you if you
can confidently handle a steeper downhill slope, I bet you'll be glad you
went for the extra control.
