You know what? I ride a touring bike for long distance commuting and own regular clipless biking shoes. But I swapped out the road metal clamps for the mountain biking ones and couldn't be happier. Road clips require you to twist your foot a particular way when dismounting. Who needs this headache? I certainly don't... particularly if I'm riding in the city. Mountain bike road clamps release from the pedal whether you twist in our out. When I'm in downtown traffic, often I just want to get out of it -- RIGHT EFFING NOW! I'm sure there is a good reason some smug biker out there has as to why road bike shoes are this way -- undoubtedly it has to do with some historical spin or something that originated for racing -- but I don't give a rip. Gawd. Look at me babble. Anyway, get the more jagged pedals for the simple reason that the smoother ones -- the ones I stupidly purchased because I thought they were more elegant and better -- greatly hold your foot to the pedal much better when it gets wet.
