Les Monts Groulx, Uapishka?

Does anybody have experience touring in the Monts Groulx mountains? I've met a few people on my travels that have recommended this place for a multiday / camping style ski tour.

Looking at maps it looks like an interesting spot. I found a bit of info on the web such as this video; https://www.youtube.com/watch?v=0CV5HW6Bq-0 and blog from a friend of mine; https://westofthespine.wordpress.com/2014/03/31/trip-diary-uapishka-mountains-les-monts-groulx/ .

These guys went in March, but does anyone have experience early season like in December? Looking at the previous weather, it's been below 0c for the whole of november and I expect that it has snowed there too. Just not sure if there will be a enough base to go exploring early season!
