One hesitation I have in more fully recommending Crank Bros pedals is that in terms of durability their record looks a little spotty. Most of the complaints seem to be from MTN bikers who often end up banging pedals against rocks and things. Not as common a scenario in the commuting world so I'm not too worried about it. I know another BF Member is switching from Eggbeater style pedals to Time Atacs. Somewhere there's a fairly detailed post explaining the reasons for his switch.
