markg, that flipping around happens to me with the Keos sometimes, and that's the main reason I have more trouble clipping in than with double sided SPD pedals. In principle, they're weighted in such a fashion that as the pedal comes up, you naturally clip in. But sometimes, a quick downstroke with my right foot causes the left pedal to flip around, making it a bit difficult to clip in. No big deal, though... just pedal around (preferably one-legged to let the errant pedal get back in position) and try again.
