Fourth Element tech fin - calling aero engineers

[Thrutch]

Fourth Element just released their new tech fin: Tech Fins Archives - Fourth Element

The idea of the bumps behind the vents is supposedly to mimic humpback whale fins and utilize the tubercle effect. But it seems like they're in the wrong place. I'm home sick instead of out diving, so I've been doing some light digging around, and I can't find anything dealing with the effects of non-leading edge tubercles like these. So, folks who study this stuff, is this a gimmick or a wavebreaking new way to fin around? Thanks!

Careful. You're going to wake Bob Evans.

Careful. You're going to wake Bob Evans.

And get informed on fuel saving pods?

Careful. You're going to wake Bob Evans.

It's like summoning a ghost, except you only need to say the name once.

Hello, I hear you. They're

missing the boat.

Anyone tried these yet? They look like an RK3 like clone to me. I hear they are just slightly negative while not being too heavy from a travel standpoint. Can anyone speak to the stiffness? I was torn between the floppy RK3s and the stiff RK3 HDs. If these are in between, they may be a good compromise.
