I have the setup you have and it is very good. I have one with the bdc and one with the bvc. Break them in right and they will be a good vape. Fill let sit for about 10 min then prime { a few pulls without hitting the fire button}. Set your volts low and do a few light easy draws then slowly turn up the volts up till you hit your sweet spot. If you wish to use watts after that slowly crank them up till you hit your sweet spot.
