ski questions

did some reading on here about ski's, well what fits what....it looks like the ZX is the same as the XP and I was told the ZX will fit the S (with some spacers) so can some one tell me if they put a set of XP ski's on there S? is the REV the same as the ZX?

The S chassis will take some spacers for Precisions and up skis but the ZX/Rev will be the same, not sure if the XPs are any wider.
