Hi all.
Appreciate all the comments and your advice (a bit of sarcasm is always good). I will prepare a revolver - in case i need it (seems easier than the "bridge idea").
We're all different, we all aim for different achievements.
I was in rush last time when posting so i'll add up some info to the above.
I've been to the summit 3 times already (twice leading commercial group, once - solo).
I would risk to say - i am familiar with French route & potential risk on that mountain but also fairly confident about the experience (hoping i don't sound smart ass). I was lucky and managed to climb much higher mountains and experienced unexpected bivouacs with only "elephant leg" in my rucksack, not even a bivi or sleeping bag.
JOHN C. - i will fully agree with you, winter changes everything including "time frame" estimated for certain section of the climb. I am also considering avalanche risk .... but thanks for pointing this out. I must admit your info about people avoiding French route was a bit of a surprise to me. Lots of climbers say otherwise - Midi route (via Mont Maudit and Du Tacul), hanging seracs, exposed, narrow ridge is way more risky than "drowning" in snow.
They also say "Vallot section" (from the shelter to the summit), which is part of the French route (very narrow passages on that ridge, exposed) is much higher risk even with an average wind blowing.
That avalanche section you have described - one of my colleagues made a cardinal mistake there recently .... see below link (not sure if you can translate sad news, sorry).

So to sum up:
Looking at the weather at the moment and the snow fall 23rd-25th (and next 5 days forecast) i am 50/50. It seams like 28th could create my "window". Still - very strong wind (increasing from 28th ... ) on the way back, is a question mark.
Anyway, i wasn't expecting such quick responses so once again, thanks a lot guys.
Happy Christmas to all
