With clipless, you are very dependent on exact, proper placement of the cleat, and then when you are riding, you tend much more to just keep pedaling forever with your foot in exactly the same position without any break. With toeclip pedals, unless you actually use and tighten the straps, your foot will tend to find its own place on the pedals. While I've enjoyed some of the advantages of clipless, I sometimes think regular pedals with the appropriate toeclip and loose straps might be better for non-racing.
