I don't get it, Davide? Are you suggesting that the "honest" way to do it is to only change glass for carbon? And that if you do other changes to the construction it would be in some way dishonest (=only marketing)?
To me that would be very foolish of the constructors and I think the sound way to do it is to consider the construction as a whole. Glass or carbon needs to be optimized in different ways, and as you know even different types of carbon will work very differently in the board and require the rest of the construction to be different to. In fact, the smaller "wave type" woodcarbon boards use a different carbon and hence a different construction overall than the bigger boards.
And at least from my side, the discussion have been about the different constructions and how they are to sail relative each other. Or maybe about how a given weight decrease affects the feel on the water. But not about if changing a given layer in a given board from glass to carbon will mean anything.
And again, the customer can choose if he wishes to pay more for the lighter construction. And at least from my point of view, Starboard has not pushed the woodcarbon in marketing in an kind of outrageous way either. It's an option that is now offered for those who want it.
