What's up Matt B! Burton did not rip off Lib as both rockers are actually substantially different.
Banana - There is radial rocker banana between your feet, it becomes flat underneath your bindings,then you have your tip and tail kicks. (C2 Power Banana would be similar to Flying V)
Flying V - There is a V-rocker (not continuous radial, as it breaks at a central point) between your bindings, then the Flying part means that there is camber underneath your feet and out towards the tip and tail kicks to help hold an edge, and then it v-rocks again on both the tip and tail before kicking upward. Make sense? I know its kinda gnarly complex.
When it comes to EGD combined with Pressure distribution edges (called frostbite) and differentiating that from Magnatraction.
EGD is switching the woods grain direction under the bindings to enhance edge hold. (think of trying to break a toothpick by flexing them between your thumb and middle finger -- kinda hard to break) That combined with a pressure distribution edges (similar to magna) in which the edge protrudes outward 1 mil to again help with edge hold. An edge technology is very important when considering rocker-ed boards! (as rocker boards are naturally more loose feeling on snow -- not as much true and tried driving power as historical camber proves)
Magna is a kindof like looking down a serrated knife and much easier to visually see. It provides similar edge hold to PDE, and shifts edge pressure away from the tip and tail.
Lets face it, I'm biased. Lib makes great product, but I prefer the flying V on Burton... I've ridden this board in all conditions and its awesome!!!
