Rode the MB-3 with the studded Nokians in today and thought it was overkill at first until I hit the frozen hardpack in the streets. Slipped a bit until I took air out of them then they were awesome even when I hit black ice. The bike path was amazingly well plowed so didn't really need them there - still nice to plow through the icey plowed snow banks at the intersections. Saw at least a dozen bike tracks on the paths so there were plenty of other crazies. So cold though that my forehead hurt from even a slight wind. Nice to avoid the car today.
