@Remi, thanks for your input! Regarding the fins that come with the Futuras, are they the C3 Venom in G10 material ?
@Phil, I am having the same thoughts as you, using the Futura 131 as a light air board and when the wind picks up, the IS107 is the board of choice. One thing i must say after sailing the IS107 compared to the other brand board of the same category...the IS107 is just amazing in terms of control, and very low swing weight. Great board.
