For scuba diving, wearing neoprene sock or true boots, I use these very old Cressi Rondine Gara:
They are both very light (plastic blade) and very powerful. At the time (1990), Cressi did make the blade in three different stiffness grades and two lengths. The long ones were for freediving, my one are the short ones. And my ones are the intermediate stiffness. My wife have them identical, but black, hard stiffness.
They are incredibly powerful, and best suited for strong currents, or when you have to carry around heavy technical equipment.
Of course inside a cave their length can be a problem, particularly if you do not know the proper kicking technique (no standard frog kicking with them).
Said that, I and my wife used them successfully in caves at Capo Caccia for 10 years...
Only problem, I do not think you can purchase them now...
What comes close to them is the Mares Avanti Quattro Plus (longer version than the Quattro). One of my sons has them, and they are good. But when I compare them with my old Cressi shown above, there is no contest, the old Cressi are lighter and faster...
