Like many of you, I have a lot of bikes. For commuting I use platforms and toe clips. It works well for me, and I like not worrying about what shoes I'm wearing. For my road and track bikes I use Look clipless pedals. That means I have road shoes with large cleats that aren't great for walking, but that's ok for those contexts.
Lately I've been debating trying out a double-sided pedal (clipless on one side, platform on the other) for my commuter to have more options. Anyone using these? Which ones do you have and what do you like/dislike about them?
