I don't do studs, but 1) around here, it's rarely icy, just slush/snow that is quickly plowed, and 2) I have 3 wheels under me so I can slide safely.
I used to just skip riding for a couple months in the winter when I lived in Seattle (and much longer in KS winters!). With a velomobile, I ride year round. I would get just a trike for winter riding as well, but I like the extra protection from the elements.
