Several years later, Son Dr Sam IV performed a series of fin test with out the stiff blade Ducks & Aqua lung, the best over all was the Plana, followed by the Jets and down the line the Rockets.
Ten years ago I published a rather extensive three part article in Historical Diver called "A short history of Fins" Tracing fin development from long forgotten Havlor Olsen to De Courlier (S) to Churchhill to many long forgotten but key stone designs of the 1930- to 1990s.
The best over all fin was the very early gum rubber Duck Foot made by Spearfisherman of Laguna Beach, then the Swimaster Voit models, followed by the early Planas, Jets and way down was the Rockets.
Which model Planas? The original Planas, or the power Planas or the Graphite Power Planas?
