Well i use a provari, a twin 18650 vv box, a twin 14500 vv box and a lavatube. All you do is add your favourite juice to your preferred atty/carto and adjust the voltage to taste and hit. I find that for me this can change at different times of the day depending on my mood or what I have eaten or had to drink. But thats the beauty of vv, you can always find the sweet spot for the combo you are using. Have fun.
