I'd love to have more info but cross sections being that meaningful is a bit of a delusion. It's marketing, Someone is just going to use it to explain why a ski is good. Maybe it's true, maybe not.
Like flipcore. It's a pre shaped core that gets turned over before molding of the ski. They just happened to name it and the name stuck
Hardly a new technique and the flipping is nothing. Plenty of things are built upside down. Boats for example. They don't call them flip-hulls.
What would be helpful is to have flexes again with actual numbers from tests. Most people in the east who ski mostly groomers are on too stiff a ski.
Having grown up in New England ... depending on how creative the snow report is ... Eastern "mostly groomers" can be pretty much solid ice that's been scratched up a little. Stiff skis and sharp edges do have their place! One marketing ploy that actually had a purpose was the famous Hexcel Blue Ice .. weird but they did work!
