I picked up a pair of Rossi Radical 9X World Cup's this summer, 2008 models. They are 181 cm and have a radius of 23m.
My experience with GS skis is somewhat limited. I found a pair of Rossi 9x Power (2004) last year on ebay for cheap and had a fun time with them on the ice and hardpack in cheese land. I then demo'd various GS skis at Alta in late March and was instantly hooked. I had to get some race skis!
Short of me trying these skis in every scenario possible, what are the limitations of these skis that you have found? I'm fine if they end up being just high speed, front face burners. If I can take them up the Tram at Jackson Hole or Snowbird, that would be cool though!
