Im using the Nokian Hakkapelitta (700x35 studded tires) and I have to say, they are overkill even for Maine. At first I was inlove with them because I could ride on slick ice up hill, but now the weight and decreased handling (on normal asphalt) have started to get to me. Unless Maine has another ice storm like we did in '98, I'll be switching to some 700x30 cross tires sans studs.
