Go down to ESS boardstore at Erina, they usually stock a few differnet sizes in the Hokua, Mark is still in Japan ATM i think but im sure one of the other boys or girls there can hook you up with a demo, i ride a 9' 5" both in a quad setup and with the Jackson Close thruster setup, both go well on the hokua IMO with the quad giving more stability on those choppy days.
Maybe try out the new fanatic pro wave if you can BTW.
