How practical would it be to mount my old alpine skis with tele bindings for lift served skiing? Skis: Volkl V3 carver 170 length, iirc 67 waist. Skier: beginner.

If your skis are really stiff (race skis) you may not like it. However, any alpine all mountain/carving ski will work for a beginner learning to drop a knee. I don't know any specifics about your skis, as I have not bought alpine equipment for a long time. Welcome to the dark side.

So Jimmy, you're really gonna do it? Let me know how goes it and I'll probably join you if the experience is pleasant.

Do it. For Volkls, those are nice and light, and ought respond well to emergency parallel moves. 22m for 177cm, IIRC, so you're talking maybe a little bit less than that. Did they have Motion on them? You'll might be able to save a few grams there.

Free the Volkls! Of course with alpine (or modern telemark) skis you will need some plastic boots, At least T2s or similar. I always recommend safety release bindings unless you are on back-country touring skis/leather boots.
