Ok, new build. better flavor but still no where near my crown... dual 24g 3mm id 7 spaced wraps at .35 ohms. first pick is finished build, second is showing how long I left the tails that were fluffed adn tucked. Top of the wick is trimmed even with the top of the posts.
Still wanting to get good flavor out of this thing... I pulled the deck out of the bottom piece of the tank and when I screwed it back it I snugged it, but not to tight. then I used a file and lightly marked on the bottom knurled ring where the center of the coils are, or rather the center of the space between the posts. when I reassembled the tank I checked and the two air holes are now at 45 degrees to the coils.
Your top pic shows coil symmetry could be better. See that opened up end turn on the bottom of the coil? The wick will not have enough compression against the coil ID right there. That's all it takes to add a burny taste to your vape and will keep you from cranking the power up to get better flavor. Also, thin and trim those wick tails on the bottom to encourage better juice flow. You may want to run at 45w, if so move up a wire gauge or two. Maybe try 26 or 28g 3mm 6wrap to increase heat flux. Your current vert build should pop flavor at 70w plus with airholes aligned with the coil. And wick um chunky!
