Last time I checked I wasn't Adam Craig, so I'm pretty sure I'll stick with normal human being gear ratios. It's getting into rainy season and the mud is going to get ugly.
On my commuter I use a 44/17 (70gi) and that's fairly comfortable for the hills I contend with on the pavement. I don't relish the thought of trying to stomp that sort of gearing (or taller) through a few inches of goopy mud.
