I am looking at getting a mermaid/merman orca tail and I have already decided on who I'm getting it from. I have an issue though, the fluke part of the tail is too small to fit other monofins, so I asked the maker and they said they could expand the fluke, but it wouldn't look as stiff like an orcas tail would and that they would make the fluke vinyl lined. So I am stuck between getting an expansion or leaving it but settling for an expensive monofin that fits the tail as is, but doesn't seem very durable. Has anyone here tried a vinyl lined fluke on a mermaid/merman tail? Can you tell me how floppy it would be or how it would move? Thanks for any responses ❤️
