hmm, i still have a lot to learn. i understand only the basics. i have a chart that i got from this site or at least this site was linked to it that shows the sweet spot or sweet band, if you will, for vaping. seems as you lower and raise voltage, resistance must also change to keep you in the zone. but i'm a newb, so still learning...
i've used top coils (ce4, vivi nova, etc...) with my ego and they can't compete with kanger bottom coils. haven't tried any dual coiled stuff.
but thanks for the reply, i am open to solution, variations and learning.
