In reply to Removed UserdoubleB:
Just like to agree with the comments here, especially from doubleB.
I've ski-toured several of the TMB sections in winter, and backed off several others.
It really is completely transformed in winter conditions, and would not be safe going solo. Indeed, several times I've backed due to snow conditions that were completely unconsolidated or crazy windblown, and I mean 'CRAZY'. On one other occasion, the wind/snow storm I got caught in felt more Alaskan than Alpine in ferocity. On that occasion, I actually was so badly windblow I was forced to crawl/wade for some distance ( i wasn't able to ski upright), and this was only about 90mins from the road..
there are lots of snow shoeing options in the Aravis area adjacent to the Cham Valley which are both much more manageable, and pretty damn gorgeous, and I have several friends who run snow shoeing days out if you'd like their info..
