Frederiks idea is correct in a way but only partly.
Its right mainly IF he means having a sandwich deck AND sandwich bottom. But many board builders have known for many years a sandwich deck helps against impact and heel dents.
By making the laminate thicker it is stiffer and resists impact. The recipe is different to maximize stiffness and light weight.
stiff and light = eps core, 2 oz glass, core cell, then 4-6oz glass on top. This sandwich can wrap the rails and deck
Impact resistant = eps core, 4-6 oz glass, THIN corecell or ply or veneer ( or even just a thick hot coat), then 6-8 oz glass on top.
Or you can just add a few glass layers on deck!
