I personally love my frog pedals so they are on both bikes but my DH who is a way more accomplished rider and gone completely back to platforms and even rides them mostly in crocs of all things. He says he doesn't lose anything inefficiency at all but gains in lateral movement and over all comfortability. It is kind of funny to see him all decked out in riding gear from his head to his knees and then hope on his carbon road bike with crocs and platform pedals but it works for him.
