I played w/ cable a little, back in my Genny days, but cable, mesh, and cotton kinda has my curiosity piqued.......
Bottom fill valve is the only thing I'm unsure of.
I like how the Taifun BT fills through the posts.
The cables are only used to wick juice up from the tank, I find if you pull out the center core they work much better.
Mesh is a blazing fast coil material and provides a very "unique" dry hit... You've never experienced a dry hit, like the one from a mesh coil. You pack a 1/4 pound of cotton in there trying to cover every possible mm of mesh and one corner is not quite touching... I'd get a clone of the BT before you shell out for the authentic.
The VandyVape Mesh RDA provided a decent vape. It needs 75W+ to come alive with a mesh coil, takes a ton of cotton and a quite a few ml's of juice just to saturate that much wick. Two good pulls and you are at the threshold of a possible dry hit, and you only need to experience that once to say that mesh coils used this way are just a stupid novelty.
The mesh on Fireluke coils and similar coils are a different story, they are chimney coils packed with cotton in a sleeve that keeps proper tension on the mesh.
The Mesh RDA is perfect with regular coils when used as a squonker, better performance and less power too.
But like anything in this vape game YMMV.
