So far, I have only one favorite advanced coil build, and this is it. It is a fused Clapton wrapped parallel with 28g Ni80 wire. The fused Clapton is 2x 24 gauge Ni80 wire Claptonized with 36 gauge Ni80. The dual build reads down to .07 ohms and does not work on all devices, as its resistance is below .1 Ω. It works fine on a kbox 120w, which will activate down to .05 ohms. Here is a photo of the build.
The rda in the photo is the Goon Rda, one of my top four choices for vaping with advanced coils. Have a nice day and vape on.
