I have eggbeaters and love em to death. The cleat is super small and they'll keep your foot in place while riding. Once you break them in clipping in and out is as easy as pie. MMMmmMMm pie.

Four sided entry is nice as well. I have the candies which puts a platform in the mix which I like.

They have never popped out during a sprint or climb, I skid and skip all day long in them. I swear by my eggbeaters.
