Surely it's much easier to control different parameters like stiffness or thickness/mass of the top with such a relatively homogenous material than it is the case with wood, so it's easier to achieve consistent results. If I understand what is stated on their homepage there is nor bracing at all: another reason for less variations.
Stability would be another key asset, no? I'd expect these tops are less influenced by humidity and temperature than wood or combination tops. I'm curious how these tops are finished, how fragile/tough the material and surface are, and how the material differs from previous CF tops, like Ovation's.
No bracing, but by "graduated" I assume the thickness is manipulated. And I'm assuming that this is how their "tap tuning" is accomplished. Which tells me that there may be some variation, though likely less than among wood components.
