I'm not looking to match my sails so much as match conditions. I want a board which will plane easily in 11 to 15 knots with a larger sail. Sometimes I can pump my techno onto a plane in these conditions but it is a lot of work and not very consistent. On the other hand, I'd like a board that jibes fairly easily, that's why I'm a little wary of the iSonics.
What sort of conditions could I expect to plane in with the Futura 141 and the iSonic 137?
