For those with the pedals that are platform on one side and clipless on the other (like the M534 or the A530) how well do they do on the side you want up staying up? Right now I love the M520s, but am thinking the ability to just go with whatever shoes I have on sometimes would be nice. But not if I have to flip the pedal over at every intersection like I used to have to do when I had pedals with clips and straps. I love being able to just stomp down and go.
