Is that actually the case with the Sanwei Paramid/F3 Pro?
Also, what is the advantage and tradeoff of going this route vs using Limba with more established thickness?
Absolutely no idea. Besides, there are more variables: composition, thickness of each layer, shape of handle, shape of blade, glue between layers, additional coating on the surface etc.
My own overly simplistic view is that top ply dictates performance of soft touches, the core/deeper layers becomes more influential when you hit harder. When you engage the composite layer, the blade would "become faster" like with the turbo on.
Having a thicker core would move the composite layers closer to surface, so "turbo" is activated earlier. Softer wood are then used as top plies to retain control for soft touches.
To get even further we would need standardized tests e.g. TTGearLab's work.
