I also use the mountain bike shoes and pedals on both my mtb and road bike. I use the same shoes for both. The only thing I don't like about clipless pedals is trying to get clipped back in after stopping at a light. I have not been able to do it without looking down to align and only on a few occasions I hit it right on. I leave my left shoe clipped in and take off when the light turns green and put my right up on the pedal which has clips on both sides but still needs alignment. I can't imagine trying to do it with clips only on one side as I'd have to check and flip as needed after each remount. I always use the mtb shoes except in winter where you need insulated boots so the platform side isn't needed.
