Also....when it comes to pedals....everyone is different. Take what people say with a grain of salt. There are 3 contact points between rider and bicycle - sort of the holy velo trinity. Butt, Bars, and Bindings. Because this is where the human body - physically un symetrical and highly differentiated amonst each other - meets a highly symetrical "machine" these areas are highly prone to mass customization to meet individual needs.
With this in mind someone saying "use this pedal system because it works great for me" is just as silly as saying "use these bars" or "use these gloves" or "use this saddle". Sure the people designing these items are trying to fit as much of the mass of humanity as possible and many are adaptable enough to work for a large portion of riders....but there is and will never be a silver bullet or single solution for:
Saddle, bars, gloves, shorts, shoes, and PEDALS. Your results may vary.
