Haha! I'd be one of those that didn't finish college. Then again, I knew what I wanted to do when I was a sophomore in high school and geared my education to achieve that. English, however, was always one of my favorite and strongest classes.

Going back on topic, I would recommend the Specilized Nimbus. I have many spots on my commute where I would like a wider, knobby tire, and the Nimbus just carries me through. It's rolling resistance is low, but not as low as a racing tire. I've pulled some major sprints and raced roadies for short distances (before I've had to make a turn) and given them a run for their money on these tires.

The stability of the Nimbus is more than sufficient for most anything you'll encounter on your commute. The only times I've wished I had more width is when I hit the occasional patch of deep, soft, silty sand. Even with the pucker moments those provide, I've never fallen over.

I don't work for Specialized, I'm just impressed by their Nimbus tire.

Oh yeah, no flats, despite my use of the non-reinforced ones and the fact I use thin tubes.
