I typically vape on house juices from my local brick and mortar. 70 PG/30 VG
My iClear 30s is topped up with Coffee, and a 1.9 ohm head, vaping at 10.5 watts. 11+ and it runs dry on the end of a good pull.
My Protank2 has Blueberry Waffles, and currently a 2 ohm head, vaping at 12.5 watts, flavor goes south past that. I have a spare base, and I'm going to experiment with some microcoils on the VTR. I'd like to get down to 1.2 ohms, which at full 15 watts should keep it down under voltage and current limits. Hell, on paper, this thing should fire a .6 at 15 watts, and be right on the edge of current limitations. Not going down that far on a PT2, though.
