The CC2 is over-rated by the internet. While they are good after the plows come, they are horrible if you're going through deeper wet snow before the plows come. It's too easy to loose traction (I can get 3-wheels spinning on my AWD hybrid SUV), until the tires spin the snow underneath to create enough packed snow to get traction. That's the downside of a tread blocks that emphasizes dry road grip, though the blocks are narrow, they are too long to dig through the denser snow to reach pavement.
maybe my expectations were too high, since I had Nokian All-weather tires before, which were literally a central European winter tire "adapted" for the US/Canada market as "All-weather", and since the internet claims these tires are legendary status for all-weather, I expected more, but came out disappointed.
Also missing in the article, even though you have enough miles, the siping pattern is good enough for tire testing, but soon after it starts to wear, gone is the stepped siping in the center area and the full length shoulder sipe becomes a 3/4 long sipe (and you can see it on one of the pictures).
