I am surprised people love their tails as much to be honest. They look nice in photos but when I saw a number of them at the california mermaid con I was shocked by how the fluke ballooned up. I didn't even know it was a tail at first, I thought it was a weird floaty, then I saw mers trying to sink the fluke so it would fill with water and have crazy drag. I also find the mahina really uncomfortable compared to other monofins. So I guess I have always been a bit surprised at how popular these tails are.
