rockered skis can still have regular camber underfoot, so basically you have regular camber underfoot but with a very early rise, so when you hold em together, base to base, the middle will be touching and then in front and behind the bindings the skis will be bending away from eachother.
Reverse camber skis have no oldschool camber whatsoever, they're completely banana shaped...
So if you hold the together it will be like holding 2"bananas" back to back against eachother, so you have a very small contact point...
correct me if i'm wrong or unclear...
and to stay on topic: i don't think theres any need to tune your edges where they're rockered, maybe just underfoot if you plan on carving them...
otherwise i'd just let them be the way they are, rubbing a gummy stone over the edges once in a while to keep rust away...
