I've ridden with ATACs on my mtn bikes for years and more recently on my fixie. I also ride Look road pedals on my road bike. They have a much better feel on the road than a mtn pedal, but the cleats are really hard to walk in. As for the Eggbeaters.... I'm waiting for my ATACs to wear out (it takes a long time), when they do I'm getting eggbeaters. They're great, easy to get in an out and you can't really clog them, only negative is with such a small platform riding them without the shoes and cleats is near impossible. I've ridden SPDs too, won't go back to them.
