FIREWIRE SPITFIRE HELIUM TECH DIAMOND TAIL "NEW 2017" Marketing Director, Chuy Reyna, was looking for all the benefits of the Dominator but even more performance. The SPITFIRE combines a Diamond tail and STEP-DOWN tail rail, giving the SPITFIRE the tail bite of a thinner board, without losing the Dominator's speed and flotation. The SPITFIRE offers the same 5/4/3 fin options and a low entry rocker for easy paddling. THE TECHNOLOGY FDS + HE2 new technology involving helium to make it 15% lighter than previous boards. The parabolic rails on the outside are a mixture of Balsa and Paulownia wood. It’s stronger and lighter than previous boards. It’s made with a new secret skin with helium in it that allows dents/foot wells on the deck so you know where your front foot goes. A really fast board.
