A lot of people like em. Not me.
I have a lot of GirvinMag SPDs, and wanted to tryout the Eggbeater Candy. Honestly the float to disengage was so large that it unnerved me. After about a month and several sideplants, I took them off. You almost have to rotate 45 degrees to get out.
I did buy a set of new Ritchey V4 Comps. The engage and disengage is better than any of my previous SPD with same float and no mud clogging so far.
Just make sure to research the floats and decide before spending. Or borrow a set if possible. I learned the hard way.
