Hi. So you'll understand where I'm coming from... I've smoked cigarettes off and on for forty years. I'm the guy that stepped around the corner so mom couldn't see. Later, I raised two children (now 27 and 28 Y.O.), and only confided my smoking habit to them when they turned 25 Y.O. (otherwise doubling the chance they'd take up the habit). To date, they've never seen me smoke. Recently, I bought a Wismec regulated 75 watt subohm mod and an Estoc tank with ceramic coils. I'd like to learn to use them to best advantage and most efficiently. However, my internet inquiries lead me to subohm cloud-chasing articles instead of the basics. vaping will not be a hobby or social pastime for me. I want to learn more about fine-tuning wattage/PG and VG mix/adjusting air intake, coil resistance options, and the effects and benefits of all these choices for regulated, box-stock subohm tank rigs like mine. Resources, please. Thanks.
