What a day!
A 6.3 would be definately faster but its not so easy to bring two rigs at the speed strip.
I wasnt expecting these speeds with a 7.0 sail.
The MXR fin is definately flying, I 'm pretty sure of it now.
Fantastic company and lots of guys setting pb's 
Tsimari can (and will) deliver even better times....
I bet that everyone who was in the water today...will be back very soon
