I'm trying to decide wether I should change my pedal system or stay with the ones that I have. In the past I have had shimano spd pedals and I didn't care for them much, but they got the job done. Then, I got a cheep pair of Look pedals and liked them so much bettter, but eventually changed pedals to the Shimano Ultegra pedal. This this probably my favorite pedal so far, but now I am considering changing to Speedplay pedals. I can't decide, what do you think?
