Ditto this. I have road pedals because SPD's hurt my feet after about 35 miles or so. I've got lousy feet and the larger platform and slightly better float suited me well. If I'm riding for distance, I won't do it without the Look-type pedal.

FWIW - I do have SPD's on my commuter which is also a road bike. I say, fit the pedal to the rider and the type of riding...not to the bike!
