How do the XC and MX models compare in function once you are clipped in? Does the small platform on the MX help, or is that just for when you have not gotten clipped in yet? I read somewhere that the MX is a little easier to get into because the extra platform keeps the pedal from rolling as you try to engage. Anything to that?

I notice that some XC models have a spring tension adjustment, but none of the MX. Does that matter?

Thanks in advance.
