OK, with a slightly shorter commute.. about 20 RT, i run Armadillos knowing full well they are heavy, not the most comfortable tires out there. I work a little harder which I probably need to do. I don't worry about every piece of glass, metal shard or thorn on my very industrial commute. I don't suggest airless tires..that is pretty extreme. But most kevlar belted tires offer a lot of protection for a relatively small trade off. Its your call. I don't much like repairing flats, especially on the side of a highway. You are welcome to.
