When I switched over from double sided SPD to road SPD-SL's, I had a hell of a time getting the pedal in the correct orientation so I could clip in. I almost fell a few times at stoplights, but now I'm a lot better (2 week later). I have the feel for when my foot is oriented correctly with the pedals and I can unclip for a red light and immediately go for a green light without delaying to clip in.
