Last year Rossignol had the 9X Oversize, RPM100, Bode One, RPM90 and Viper X Oversize (which was only available in Europe & was Rossis top selling ski there). All 5 skis had the same dimensions. The 9X Oversize and RPM100 are suppose to be the same ski with different graphics. The RPM90 & Viper X Oversize are also suppose to be the same ski. I have heard two different things about the Bode One, though. Some people have said it is a repackaged RPM100 while others say it is a repackaged RPM90. My guess would be it is a repackaged RPM90 since it is being sold as more versital than the 9X Oversize and better for bumps.
