Me too! I'm actually thinking about a winter bike, not just winter wheels. Even though there's a big storm coming our way, I went ahead and took off the studs this weekend. There were quite a few days where I was happy to have them, but there were far more days when I was wishing for a separate wheelset or a winter bike. Plus having separate wheels puts less wear & tear on the special tires-- only use them when they are needed instead of all winter.
Even if we get a lot of snow, I don't think it'll last very many days, and I'll just walk until the streets are clear.
Boy howdy I was fast and quiet with my regular tires. Then even faster when I came home and had that wind at my tail!
Edit: By the way my back is fine now. I took 2 weeks off the bike and no exercise. Slowly ramping back up the exercise now, carefully carefully. Biking to work is no problem.
