Working toward Cenotes
Split fins apparently make things like reverse kick and helicopter turn kicks difficult. Each is very handy even in open water for maneuvering around things in the water or around buddies. But cramps are bad things. Trade-offs.
(ForceFin Pros or Flying Force fins are very cramp resilient, though expensive! On currents, I could calmly hold position or swim against current that had other divers and guides sheltering behind rocks. They also fit in carry on. Not the average diver gear.)Yes, there are always recommendations of what to do to avoid cramps (hydrating, diet, exercise, etc.)-- which don't necessarily work if cramping is hereditary.
