I know Dave. His fins are built to his standard of excellence. He needs no quality assurance department because HE makes everyone of them himself. At least he used to. He could sell out to someone and they could mass produce them. But they would then be Kashy fins in name only. Anyone who takes a sport that is as fun as windsurfing and turns it in to WORK (i.e. racing) deserves to pay the price to win. If you want the best gear money can buy then..well...pay or make your own.
