Despite staying in Zermatt many times (my favourite ski place), I've never skied from the Monte Rosa, which isn't served by a lift but looks magnificent. So that's my dream peak.
In terms of off-the-shelf piste/trail skiing, the black run from the Aiguille Rouge, above Les Arcs, down to Villaroger (around 2000m vert) takes some beating.
Re. the above nominations, I can endorse La Grave and Verbier as choices. They're both wonderful.
I had a trip planned to the fantastic off-piste resort of Alagna, Italy, a few weeks back but had to cancel. No snow.
