My recommended build if you are running a mechanical mod with a Sony VTC series battery: dual parallels 4/5wrap around a 3/16" bit. Comes out to about 0.12-0.14 ohms when I do it.
If on a 20-25A battery like a purple Efest or LG or Panasonic or Sanyo or something: dual parallels 5/6 wrap or 24g core clapton coils
If on a regulated box mod of 50W+: dual micro-coils, 4/5 wrap, around a 1/8" bit, set in at a 45* angle. You can try claptons, I haven't yet. I have my 100W box set at about 75W; perfect balance of clouds, warmth, and throat hit, but that's with a dark horse rda and a butchered tobh v2.
In my right (more like wrong) state of mind, I'd say dual 3-strand twisted 24g 4/5wrap coils, but I'm not sure you'd want to go there.
Good luck and let us know what you decide on!
edit: forgot to say, don't wick any of these with poor quality silica. You'll just get dry hits all the time.
