Ta for the reassurance P.G. Three of my current crop of boards are Exocets, so I like good news
With regard to construction; surely shorter wider thinner boards have no right to be lighter than older shapes OF THE SAME VOLUME! If they are there must be less material, or greater use of carbon. [Unlikely in todays harsh economic climate.]
One change from the 80's/90's is the use of lighter less dense foam. I sawed my 1989 custom Lightwave wave board in half [obselete shape] to see why it was so strong? Clearly, the very dense and heavy foam combined with the epoxy skin worked together with a degree of flex. Apart from constant epoxy dings it survived my learning to jump unscathed.
Might this constant striving for none flex stiffness nowadays be compounding the fragility problem? After all, Oak trees and Willow trees and all that!
