What exactly does this mean?

:( what does "Proprietary parabolic focus flex zone " exactly mean? I see it all the time as a way to advertise the Z-Bubble, but what is it?

Marketing crap.

Proprietary means they own the technology

Parabolic means curved like a parabola

focus flex zone means that it flexes in a specific place.

In short, it means that their stick uses a technology they own that that curves and makes the stick flex. The reason it curves, also happens to be where it flares out to accept standard blades.

so focus flex is all marketing jargon? what would you suggest for a composite blade?
