Does/has anyone here used them for winter riding? I currently have touring tires (panaracer pasela) on my bike, which has made the ride to work exciting the last few days (we got 18 inches of snow since Tuesday night). Since studded tires are too expensive, I am on the look-out for traction, which I thought I might find in cyclocross tires.

I could switch to my mountain bike (ridged, basic mountain tires), but it is small for me, doesn't have space to mount my lights (I have two, and one needs space for a switch), and needs new shifters and brakes. Would this be a better option?
