A lot of people around here really like the Jet style fins. I've always thought that the fin vents would be an entanglement hazard; especially on wrecks where you have dangling wires, or metal objects to get impaled on. Anywhere with low vis and swift currents would seem to make this worse.
I know some one will reply that your fins should not be near the bottom anyway, but your fins should also not be near the line, and it is common practice to reverse and tape your fin straps, or replace them with spring straps. Entanglement seems to be a big point raised whenever split fins are discussed as well. So why aren't fin vents ever brought up as a problem?
The other question is: what's the point? I can't understand what sort of physics advantage the holes in your fins would give you. They sort of seem like the "fin gimmick" of the '80s that just never went away.
