Yep, it's gonna be fun to try all the possibilities with this. It might hurt my OCD to break up the StingMag. I mean, really - it's The StingMag.
I noticed already that the Aqua can handle more power than the ErlPrinz. When I go higher than 12.4W, the ErlP starts to taste "off." I have PB + Legend blend in the ErlP (Legendary Booty, Copyright Bunnykiller) and I normally vape that in the 15W range. At that level in the ErlP, it tastes burnt.
That's probably airflow. The ErlP has a lot of airflow, but it's all coming up from the bottom. (Where it leaks and condensation forms on your mod's top connector - not loving that.) Side airflow in tank mode with the Aqua and increasing wattage is no problem.
The ErlP will be my Provari tank, which will be just fine. It works better there anyway, because of the Provari 2.5's top cap design. It allows for a little less restriction on those bottom airflow holes.
