Hello and Thanks in advance... I have an older pr. of shimano 747 pedals which finaly need to be replaced. They are good pedals but not in mud. So OK shimano is my first choose, but there seems to be so many options like crank bros. candy's, eggbeaters, time, etc.. So what do you all use? I ride rocky technical terain. I am between shimano 540's and crank bros. candy's. any help would be greatly appreciated.
