Heres the deal, I have both , 2002 sc10 III and a 2000 Cat skid. I know that the Cat skid has been the most popular to put in a Yami, but would like to hear any comparison input. I dont have any seat time on the newer ZX ski doos to know how the rear handles the hard core studder bumps and wooped out corners. Installing on a Viper S. Thanks for any help!Dave
