hmm. have you used Time pedals?
they function in a very similar manner.
don't get me wrong, i liked using eggbeaters, but when i sheared the spindle in half ( like half it's length, leaving a jagged end sticking out of the crank, and fortunately not into a bit of me ), on a climb i pretty quickly came to the conclusion that i didn't really want to persist with them any longer. not an easy decision to make when you're then into changing pedals on five bikes.
i persisted with eggbeaters for 5 years or so, serviced them and looked after them, i still think the actual function of them is very good, when in good condition, but i had to draw a line under it all in the end.
