Wood.

This is a pic of Paul and Sage at the Wood fry Last year. The board that they are holding is a 7'4 Alaia made from one piece of Redcedar. The board is amazing and the craftsmanship is unbelieveable as Paul uses all hand tools and general perfects his boards down to 1/64th of an inch to perfection. I am yet to ride this one  but I'm sure its only a matter of time.
