I've briefly tried mesh coils over the years and never liked them. I always got some sort of metal taste in the vape even after scorching it with a mini torch. I used cotton wicks for years and finally tried Rayon ... I'm sold on it.
I'm sure there are many better tanks for MTL, but I'm still sold on the Kayfun 2 and the Beserker MTL RTA.
One of the worst experiences I had with mesh was a tank that I can't remember the name of. The mesh had to be rolled into a cylinder and the wire wrapped around the cylinder. I never got it to produce anything resembling good flavor. I"m sure I did it wrong, but it's in a box in the closet somewhere today.
Simple is usually better for me. That means an SS316L single coil with a rayon wick. It suits my MTL vaping style just fine.
I use the same build except for DL lol!
