I just got my LM-22's on last night - just in time for the 2 inches of ice, covered with 4 inches of snow. When driving to the shop on my stock tires, I had to go extra slow, and almost got stuck in NTB's parking lot. Driving home, I was going 50mph on the highway passing everything on the road. I wasnt being unsafe doing this either, these tires are awsome. I wish I could help you with the sottozero's, but I can definitely vouch for the LM-22.
