Here, the Hadaly "killer" has been achieved. Enjoy! And please excuse the poor photography.

5 wraps, 4mm ID, 2x26/38ga. Ni80 @ 0.34Ω. And in the end, it's not a lot different than my Hadaly build aside from an increase from 3 to 4mm ID and a mild lift to ensure full clearance of the airflow.
Speaking of clearance, you can see I've been generous with the rayon, and there isn't much more than about 0.8-1.0mm of clearance between the deck walls and the coil (be careful, fellow mekkies!). The air has nowhere to go but up and around the coil and straight to the taste buds.
This thing crackles like something else, yet it's actually nice and tame, suited for a long, easy draw. Even with the SS wide-bore tip, I have yet to get a drop of juice in my mouth.
I still haven't found a single reason to close down the airflow. I'm a fixed airflow guy, for sure, but the AFC here is really odd. Negligible changes in draw until you get near full closed, and with this particular coil, anything less than full-open is a lesser vape. Maybe higher resistance coils would be over ventilated, making flavour suffer unless closed down? All I know is the perfect restricted lung hit is basically available at all settings and that's just fine with me.
Took a wrong turn along the way and chased after a dead end, but I got there. Now to enjoy this coil for a few weeks and see if my conclusions prove hyperbolic. <3
