ss mesh tastes like shit, never tried ceramic.
i like using multiple thin wires twisted into one, then use that twisted wire to make a coil, it greatly increases surface area, and creates cavities for the warm oil to capillary into.
Temp control is key with the ss mesh, but i will say i like the FC2000 ceramic wicks way more. They hold A LOT of oil and have almost no taste when ran dry.
There's some cheap temp control mods coming out, you can get a 50w temp control for ~$35. Pair that with some titanium wire and ceramic wick and you've got an awesome pen that anyone can get a good hit off of. No more pulsing the button or getting hot burnt hits when it runs dry.
