As for crankbrothers they have 4 pedals on the market, each with their own differences but all containing the crank brothers clipping in design.
There are the regular egg beaters which are pretty much the epitome of crank brothers, thats the link i posted in my previous post. There really isnt any platform besides the clipping in place. Since the contact patch is so small, you will want a stiff shoe.
The Candy Series is the same thing as the egg beaters except it has a little platform around it. I opted for these because sometimes i ride with sneakers for short distances,
I need some sort of platform for that.
THen the Mallet which has a large platform and i think looks odd. Crank bros says its for DH use (on their website).
They have the "road" one called Quatro but i dont see why its all road
