Best Monofin for a tail?

[MermaidIndie]

So this should probably go in the Monofin section but apparently I don't have permission to post there or something. Anyway theoretically if you were to start a fabric mermaid tail business what would be the best types of Monofin to put in it? I'm not attempting to start some big tail making company but locally I've made several tails for people. If I were to start doing this more regularly what would be the best type of Monofin to put in the tails?


The crash of waves and salty air are the signs of freedom

You have many options, Finis Wave/Rapid, Finis Mermaid fin, which now has adult sizes too. So Dive Triton is also a popular choice.
Mahina Monofin is made of recycled rubber and has a fun shape.

For fabric tails id recommend the finis wave/rapid or the so dive fins. The so dives are really nice because of no ridges, but they still have really nice propulsion
