Garth,

The lighter rims will let you out-accelerate your bud, all other things being equal. I would think that once you pull ahead, the aero difference is too small to matter, so he would be forced to ride faster than you to catch up. He'll have a higher worload over the course of a ride. I'd be real surprised if the spoke aero effect is large enough to matter, but I could be wrong.
