Oh
Dusty, I've build them all

Gave multiple setups to my Kayfuns and the Russian... tried everything and ALL WORK PERFECTLY. Which is why I repeatedly post here that the Kayfuns are fail-proof, fool-proof and non malignable!

Currently all my Kayfuns (and the likes) are running
Vapdvrr's Microcoil with Cotton (Build-
4 above)! Ether the regular Cotton Ball types or with S&C Cotton Yarn. Each has 28AWG Kanthal with 10-11 wraps on a toothpick, reading 1.1-1.3Ω. And I'm overtly happy with the device's performance.
Surprisingly, none of the builds were any better than the other. All gave out similar, if not the same vape quality, which is, "
a perfect and most satisfying vaping experience"
! I chose to stick with Microcoils & Cotton purely b'coz:
1. It is easier to build,
2. Easier to maintain (just replace the wick!),
3. The coil remains put for months (just dry burn it during every wick change),
4. No more running around searching for Silica, EkoW, Bastos, whatever. Cotton is omnipresent,
5. Saves on time, effort and money

BOTTOMLINE: Kayfuns are a design marvel. A 'game changer' like you stated once. Gone are the days of messing with builds, tilting to wick, keeping the mods upright, thinking of whether or not to keep the fill-hole open, what ratio the PG/VG should be and such vagaries... it just kicks / clicks everytime. There are
certain tips, for the Kayfuns, to give it's best though. I've posted them many a times earlier. Shall repeat them once more in a subsequent post.
