I can't think of anything to add to this post. If you're in "Thornville" USA, the plus is the way to go. The standard Marathon tires do have a really effective kevlar belt, but the pluses are definitely a step above in terms of flat protection.
And for the record, our entire Marathon line of tires come with the reflective ("reflex") sidewall. In fact, it's the only way they come.
