Since you're talking mesh, a few notes from my Cthulhu Ceto experience. I've only been using the 300# SS 304 mesh that came with the atty. I've tried several builds, different diameters and mesh widths, and came to the conclusion that Ceto was not going to do it for me on Coppervape, even the one I converted to 20700 (with high continuous amps). The ramping was still too slow on the smaller mesh build, and I couldn't get the warmth I wanted. Now Ceto stays on Dripbox 160 @ 80-120W.
Ceto is a fantastic vape though. Huge flavorful vapor and super smooth because of the vertical orientation. IMO a horizontal mesh coil in the Vandyvape above doesn't seem attractive to me.
I'm still going to try some Ni80 mesh on Coppervape when I get my hands on some. I expect it will ramp faster, and might just get me the warmth I want on the mech squonkers I prefer.

Looking at this photo reminds me of a surprise benefit of big mesh coils. All that wick holds A LOT of juice, like a small tank's worth. Get the thing fully saturated and squonking is about as infrequent as a BF RDTA.
