Nice application of graphene. It is springy, soft yet very strong. Could be used for surfboard production? Obviously with some modifications..;.or just make a shell with graphene and custom design in any flex patterns.

Actually I always wondered why in all those years of surfing industry, still we get styrene (with pros and cons) and foams like "clark" "bennet" etc... again with pros and cons.
