assuming you use quality battery I'd use SS316L tri core clapton wire 28ga/36ga and doing 3mm id 5 wrap parallel build
Not knocking fancier builds here, I'm not. Only saying I can do well using plain old SS316L, 26ga at 3mm ID, 5 wraps. I get between 0.30 to 0.60 ohms on that and usually average out at about 0.45.
It produces good vapor on a mechanical for me, the same on a regulated. In both cases I use a decent 18650 single cell. Then, currently I'm using max Vg, switching back to 50/50 mix though. I'm not really a cloud, or flavor chaser.
I vape because it's a cleaner, safer way to use nicotine. Realize this is merely my humble opinion. As said, not knocking anyone else's style or way, only adding another way to consider.
