I would not be sacrificing the advantages of a monofin... I'd figure out how to have someone custom make me the "ribs" of the fluke, and combine that with foot pockets as if it were a monofin. Then I'd just have silicone "draped" between and... I'm thinking it would work as well as any other tail with a monofin in it. However, that was before I knew that monofins could come clear. XD Or maybe I could make a clear monofin or commission one... instead of all the complicated stuff I was thinking of doing.

So I'll maybe do it instead with a clear monofin... just super worried about it showing. It'd definitely be cheaper to do it that way I think.

(And no, I'm sure I'm a lionfish, not a stonefish. That was actually really funny to me though- thank you for the laugh!)
