well...
after all the feedback and reading tons of posts on the internet, I have comme to the conclusion that for dedicated snow tires the Blizzak's are better than the nonkian wr, but if someone wants to compromise the snow/ice handling to get all year tires then wr's are the way to go.
since I'm looking for tires that will perform the best in snow, I will stick to Blizzak's. For other season I have the all season tires that I will put back.
thanks for everyone's replies.
