RE: 2008 isonic's
I think Starboard is not changing unless it, in some given perspective, is necessary. Every year there are a boards that are not changed simply because no protos tested significantly better than current models.
But it is still a fact that for slalom and racing, the margins are smaller. In the PWA slalom 42 format the racers have to use standard equipment and for these sailors, winning is everything. I would rather say its a challange to design the stuff to have world cup winning speed and still be easy for the general public to use. Both S-types and iSonics are proven success stories when it comes to this.
