Thanks for the walk down memory lane. My first board that I bought new was a red plastic fantastic, 6 foot single fin, purdchased in huntington in 1970. It cost around a hundred bucks, and a full body glove suit was 30, and wasn't worth ten. It was still better than spending the winter hypothermic, which I did for the 4 grommet years prior.
The only thing I disagree with in the article is the connection of modern shaping to the historical hawaiian, I don't see it, maybe in the 40's and early 50's, but not since the introduction of fiberglass cloth and resins. Certainly not since foam.
