small front tire; large back tire

I won't pretend to know much about this, but wondering why you want a smaller tire on the front? It won't impact wind resistance or speed or rolling resistance much at all, while reducing comfort. I remember an article by sheldon brown analyzing tire width and pressure (this was focused on touring, not racing) and basically there were was all sorts of complicated physics involved, but a larger, wider tire can be lighter and faster than a more narrow one, depending the sidewall.

I figured a thinner tire with no treads would produce little to no rolling resistance hence faster and smoother ride. Of course, correctly inflated tire would only improve that. Ahem, I have never said I made it though my college physics class.
