Sooo,
Let me get this straight. You get the concept in 1967, fiddle with it until 1969/70 when you “spring” it on the world and begin to promote it. Here it is more than a third of a CENTURY later, and the WORLD SURFING COMMUNITY has not embraced your “breakthrough”. The market is telling you something. Actually the market is screaming at you, and you seem not to hear. Is that what you call getting real? The appearance of the device gives the impression that you are channeling Rube Goldberg. However, I did see some good advice in this thread, KISS.
