Always good to try new things. So far, the lowest I have tried that doesn't change/wreck the flavor is around 1 on the Black Clove but only as low as 1.2 on the P-38. Aromas flavors are so complex (yummy). Not worth burning IMHO. That said, more experimentation will occur, as
vaping has become a hobby.
I also have found that my flavor far surpasses my desire for gigantic clouds and this is best achieved on a smaller atty atop my Reos. (14 mm). I tried a larger atty and while I filled the room with vapor, the flavor was muted (and I ran
thru
juice like there's no tomorrow).
Everyone has their sweet spot. The fun is finding it
