Okay. See from the small bit of research I done I was under the impression that higher vg was better. But there's a massive amount of false information out there. Mant many people said the istick wouldn't even work for the aspire Atlantis. But at least now I am better armed with information, and will not allow the vape shop to talk me into stupid buys.
So for that I thank everyone who had some input on everything, it's greatly appreciated.
Higher to max VG (usually 70-100%) will give you greater vapor production. Its also more viscous (thicker) than PG. Clearomizers and subohm tanks don't seem to play nicely with heavy VG juices because of how thick it is. This results in a dry hit more often. PG, being less viscous, can wick better so you can chain vape for a longer period of time before getting a dry hit, if at all. PG gives a better throat hit while, at the same time, dries out your throat. Make sure to drink water.
40/60, 50/50, and 60/40 are probably going to be your best bets for your Atlantis, though you can try 30/70. Also, PG usually comes before VG. I assume its because its alphabetical ('p' comes before 'v'). So 40(PG)/60(VG), 50(PG)/50(VG), ect...
TL;DR
PG is more friendly with tanks and VG gives you better vapor production. And drink water.
It is so bedtime...
