bloody hellfire, how heavy are those Time pedals! over 1kg the pair - do they do a mag/plastic version?
candys have no platform. if you use disco slippers you shim the cleat so the shoe tread rests either side of the springs to offer support. to be honest i dont see the point of these pedals over eggbeaters other than to offer protection to the springs.
if you run flat pedal shoes you may find you cant do the support thing above and it feels a bit wobbly (as the tread is generally less deep). Also as you weight the pedal the springs press apart which means you go through cleats quicker as they need to be less worn to work. since i got disco slippers for the xc bike i found i can re-use the old cleats on my mallet setup fine when they were blowing out of the candys (same shoe - vans warners).
