I recently bought a subtank mini and istick 30w. The combo is great but the subtank has far too much airflow for me. I didn't know beforehand that a lot of people lung hit it, which is too hard core for me. Has anyone gotten it to work well with mouth to lung hits? I've tried the smallest air hole and even half of that is too much and I end up coughing. Even the 1.2ohm coil with 1/3 smallest air hole didn't work so well, had no vapor at all. Is it worth messing with or should I just try to trade it for another nautilus? It's a shame because the flavor was the best I've tasted yet. I need verticle coils or cotton, can't taste much any other way. Comming from nautilus and dct's.
