Thank you all for the pointers. I actually don't need the fancier capabilities (I vape at 5.6 Watts for everything except trying to get an extra day or so from a gunking-up atomizer with a few high-wattage puffs), but it might be nice to have the name of the juice displayed to aid in identification when vaping in the dark (movies or night driving).
I alternate between two eVic/ViVi Nova rigs (w/Sour Cherry 36 and Sour Green Apple 36) because I generally vape hard/frequently enough to over-heat a single atomizer. A little extra cool-down time between puffs seems to give a pleasanter vape and prolong atomizer life, at least for me. That also lets me refill tanks and swap batteries only once per day. I run a pair of 2000mAH 18650s down to about 15-25% and nearly empty the two 3.1 ml VVN tanks in 24 hours.
(Three guesses which tank has SC and which has SGA.)
I used to need
three sets at a time back when I was using "stick-n-carto" rigs (everybody starts out with something inappropriate, don't they?); they would get hot enough to burn my lips otherwise; they needed to be swapped/replaced two or three times per day. Loading up my pockets in the morning was a real production, and maintaining my vehicle/emergency back-ups was complicated, to say the least.
