I decided to give the new CB Candy a try
Compared to the other pedals, it was lightest and least expensive
It's just a composite resin wrapped around an egg beater. Shimano has a similar pedal, the M-424 that they call it an off road sport pedal. A friend of mine had the Shimano pedal and while he is a good rider his resin body on the 424 broke after 6 mos of use, and he doesn't ride that often. It will be interesting to see how long this resin body lasts on the Crank Brother pedal.
