Yeah I haven't had cool weather spook me too much (I know it's bad for the summer compound, but I never actually felt like traction was seriously impaired even if it's a tad below freezing) but the main thing I don't like is if I'm driving several hours in mild temps / dry roads and then get to my destination at altitude (ski hill with snow for a parking lot) because then I'm either wasting away my snow tires for 99% of the trip or I'm a stick of butter for the last 1% of the trip! Not to mention, the Blizzaks hydroplane like crazy in the wet due to lack of longitudinal sipes. So yeah I think I'll go with AS4, DWS06, or similar.
