gobrigavitch, have you read up on tirerack.com about the difference between Studless winter and Performance witner tires? Also Car and driver had a good article on witner tires http://www.caranddriver.com/features...mparison_tests
I debated Studless (Nokian Hakka R or Michelin X-ice) vs Perf winter (Blizzack LM-60) and decided to go with the LM-60s. My reasons, I am pretty confident in the snow and ice (Ice raced for years, drive with stability control off in winter) and would rather give up some snow/ice performance for crisper handling in the dry. For a perf winter, the LM60 leans more to snow/ice traction, less dry traction then the other perf winter tires.
