The thing to remember with any atty, especially RBAs is F.A.C.T.: (wick)Feed, Airflow, and Coil Temp. You can get clouds with just about any set up, but there are physical limits. I've seen some decent clouds from guys using a 306 or a .357 but they don't come anywhere near the dual coil sub ohm bored out RDAs. So all you need to remember is that there is a balance, you need fast wick feed, open but balanced airflow, and hot coil temp. This T.O.V.E. (triangle of vaping efficiency) is raised or lowered to suit your gear. The guys getting big clouds bore out their airholes (around 2mm), have super hot coils (around .6 or less ohms) and use really fat wicks to deliver juice fast enough to not starve their wick and coil.
I read all the time vapers who wonder why their 2.5 ohm whatever isn't giving a big clouds even if they push the volts up on their mod, all they get is burned taste. It's not one thing but all 3 factors that dictate vapor production. Their 510 connector breathers (atties that get their airflow through holes in the 510 connecter) just can't supply enough air over their single strand 2mm silica no matter how many volts they pump through the coils. It's simple physics.
I can get good clouds off a fresh clearo, and it may look impressive on a pict, especially when the light source is infront of the cloud to make it look more opaque than it really is. But it isn't close to that warm thick milky london fog pea soup cloud you get from a dual coil dripper with a fat coil with twin 2mm airholes. True, the more VG you use the thicker it is, and Ive always been a VG vapor; I don't give a crap about throat hit (being a hookah enthusiast for a couple decades, I know what real clouds look like and if you get throat hit from a hookah, you are doing it wrong, heh), But I can get decent clouds from a 50/50 mix; the gear is more important than the liquid mixture in production. And yes, I dropped my nic from 18 to 6-8mg since cloud chasing. And the stuff about not getting a desirable flavor from big clouds, that would be a big false. Again, it's about your set up. On a dual coil, I make a U shaped squid wick and get way way more flavor than I ever got on a Vivi/clearo/atty/etc. So if you do all your research, understand the inherent dangers and take the necessary precautions, get rid of the mouth draw mentality, and kit up with the right gear, you will no longer be asking "how do I get big clouds", but rather "why hasn't someone told me about this sooner?!" haha cheers mate.
