I've been using pedals that are clipless on one side and flat on the other for the last few years. I think that they're great. I had heard that you need to get used to them, so that clicking out becomes an unconscious act when you come to a stop. So, the first thing that I did was to spend a lot of time starting and stopping in a parking lot. Click in, pedal for a few feet, then click out and stop. Repeat. It was a good way to learn for me, and I did no Arte Johnson falls.
