The guys that trackstand with clipless are just effin nuts. And i'm not talking that cheap inchin forward little by little trackstand. I'm talking stopping dead on, with no movement at all. I can do it decently well on my toe clip pedals and my platforms, but it still rattles me to do it clipless. I have to cheat and just inch forward till the light changes. Mainly because I'm certain I'd fall off my bike 1/10 times.
