If I choose to get snow tires for my Crosstrek, Which ones should I get or are they all about the same? Will the stock all seasons be good enough for Northwest weather. Anyway, some of my choices are (spelling may not be correct) Bizzaks WS80, Ice-X Ice3, Continental Contacts, Nokian Nordman 5's, Hakkapeitta 7's, Hakkapelitti R2 or 3's. Those are my choices....any advice?
