With regard to the article, the conventional wisdom in the mid '70s was that stiffer is better, alright. Track-bike clearances on road bikes became kind of a fad. When I built Fredo in 1976, I didn't want to go that far, but wanted a stiff frame, especially since it would have the disadvantage of a large size, 26", or 66cm. I went with 75°/75° angles and a fairly short wheelbase of 39.5", which still has no toe overlap, and can run 28mm tires in the rear.

One other thing Colin Laing had me do was use a straight-gauge, not doubled-butted, tube for the down tube, Columbus iirc, with the rest of the frame being Reynolds 531.
