I would suggest Green Smoke, but I have NOT vaped their 0mg strength cartos. Excellent vapor production (for a cigalike, still not very much compared to something better), and better flavors than any of the e-juice I've tried since leaving green smoke behind. Downside: Not compatible with much (808D2 threads, almost nothing that works with that crap), high price like most cigalikes, short battery life like most cigalikes, etc, all the problems with cigalikes.
