I was at the Burton Mountain Festival demo weekend at Mt. Hood Meadows this past weekend, and tested out the Restricted Cartels. When I was debating whether to demo those or the Vitas, The guy that set me up with them explained the Vitas are softer--so I went with the Cartels. I heard the same thing from a shop kid at a reputable local snowboard shop.
Then you've got people on this forum saying it's the other way around...so which is it?
