Apparently it's an old story: I started SS, flipped the hub one weekend, have never gone back.
That said, on really rainy days I ride my Rocky Mountain with fenders, rack, bell, and other stuff on it. It's nice to get the variation. If I had to have one bike I'd have gotten something with clearance for fenders and I'd be switching the wheel around at least occasionally.
I've got two brakes, but I'm weird and have Grip Kings instead of clips. Getting curious about the clips though, so who knows?
It's a bike, it's a flexible beast. Fit what you like and change it if you want.
