I am looking for a new set of pedals for the r700, I am considering the Look Keo sprint's, and speedplay X/5 and zero cr-mo's. The question is will these pedals be safe for a 230# rider looking to be 220lbs? Also opinions on the pedals would be appreciated, or any other suggestions for pedals in the less than $150 market.

On a side note I did search a bit but mostly reviews were found, and I am mainly looking to see if these would be adequately strong for a clyde, seeing as they are relativley light.
