Think Bundy and Glenn use a mark 4 and they are definately leaders? For a low-wind event like the games seems to build up to, they might be looking at flatter shapes to get a better L/D ratio when going downwind. Power dont always equal speed so that might be it. Dont see why they are not happy with the existing spi poles though.

It is so sad to know that multihulls are out of the games. I'll miss the experiments done in the Tornado class and the mind-food they have created.
