I normally vape 70/30 Vg/Pg eJuice and I was finding that no matter how I wicked and coiled this atomizer the tank would vape great till the liquid got down below 1/3rd full and then it would start to dry hit even after refilling. I pretty much gave up on the tank, but one day in a live chat someone stated I should increase the juice flow holes in the deck. I clamped the deck onto my drill press and increased the 4 holes to around 1.96 -2.00 mm dia. and bam - this atty is my favorite with no dry hits at all anymore. This is not a solution for most, and I would not attempt it unless you have a drill press and a good set of numbered drill bits. If your tanks wicks fine then no worries. This was a hail Mary attempt by me to rescue a tank that was headed to the bone yard, and it worked.
