It seems that alot of riders use the Shimano XTR's or Crank Brothers Eggbeaters or Candy pedals. I have the Crank Bros. Candy SL, which have the same features of the Eggbeaters with a bit of platform. When racing, they are easy to clip in and out of. Also, they are lightweight and shed mud and debris very well. For the money ($65 new on ebay), I would highly recommend them. I also like the fact that Crank Brothers sells a rebuild kit for $15 that makes it easy to keep your pedals feeling like new.
