What coil Ω's and wattages are you using with the 26g SS316L?
I mostly use SS316L. 27g single wire, 26g single wire, 26/36 Clapton and 28/36 Clapton. I prefer 316L because I can take an RBA from a mech to a regulated mod running TC without any changes.
And for me, SS316L vapes cleaner versus kanthal. I never liked kanthal, it had an obnoxious metallic taste that I did not like.
My
coils range from 0.5Ω to just under 1.0Ω.
Using 26g 316L I have no problems
vaping from 14.5w to 30w (MTL/RDL/DL) on a regulated mod in TC or in wattage mode. Thinner gauges I am around 10.5w - 18w. Just depends. With regulated mods I mostly vape in TC, occasionally in wattage mode.
With lower ohm
coils (ex. 0.5Ω) I use Samsung 15A and 20A, Sony 25A or Molicel 35A 18650 batteries in mech and regulated mods.
I do use Vapcell 10A 18350's in a few mechs, but I never run builds lower than 0.6Ω with those.
18500, 20700 and 21700 batteries also get used in mechs and regulated.
