I'll bite . I loooove my speedplay light action. Extraordinarily easy to clip in and out of and I really like the amount of float.

Now the caveats. I have had issues with hot foot and it seems that this isn't entirely uncommon with speedplays given the smaller platform. I found that stiffer soled shoes helped immensely with this issue though on HOT days I still have some problems. Whether on those days its a speedplay thing or simply a hot day thing (I HATE riding in the heat) I don't know.

Second, these are the first and only clipless pedals I've ever had so I have nothing to compare them too. But if I thought they sucked I would have replaced them by now!
