So I've always kind of liked my Protank 2's, and compare everything to them as a kind of a baseline when try new vape things. Lately I've been running slightly larger than stock diameter coils wound from the res-no res wires that I re-purpose from my gunked Nautilus coils, but they run a tad warm so have been running them at slightly lower voltages on my ProVari's. It dawned on me to drill out the air holes on the airflow bases. I've got seven of them drilled out now and those things are just singing. I'd easily compare the vapor and flavor to the Nautilus tank, if not a tick better. I love tinkering with the vape things
