I like to find a wattage I like first, use ohms law to work out what voltage it's dishing out and them change to vv mode and tinker with it a bit as the voltage adjustments are smaller and therefore you can find a more refined vape
I would stay in watts mode and make sure you are in rms mode and you will get better flavor. Everyone's different but most people sweet spot is around the 8 watts mark :-)
