I'll save you the history of what I vaped, but it didn't take me long to vape silica ( I use cotton now though ) rebuildables 99% of the time. I just really really love them, so much more than any carto or clearo I've ever tried.
There can be a fine line between 'chasing clouds' and actually having a really great vape. Blowing big clouds is fun, but I find that flavour CAN take a hit. I've had some builds where I get great vapour and really great flavour and then some others just seem to be all about the vapour and not much else. Something to realize too, and I don't think everyone thinks about this ( I know I didn't really at first ) that the bigger your vapour production the more juice you'll use. I know it sounds stupid to say that cause it's obvious, but blowing big clouds all the time does tear through juice. You can sit down and in and in just a few minutes burn through at least 1ml sometimes 2ml.
I know some people might poo poo this, but what I'm about to say is just my opinion and the style that I've chosen to vape mostly, and by no means does it mean that you should follow suit.
I think that easiest way to get big vapour is to go dual coil and sub ohm. Right now my trident setup is sitting at .4 ohms and it's performing really really well. I will say this, if you chose to get a dual coil RDA and try some sub ohm builds on it YOU NEED TO DO YOUR RESEARCH. Like you really really really need to research the hell out of batteries and how they work and what resistance does to your amperage and wattage etc etc. Just please do your homework. I've seen many posts about people talking about these builds where they don't meter out any ohms and they don't know how many amps their battery is capable of, but they're like 'omg huge clouds' . All fine and well until their battery over heats and they have a really bad day. DO YOUR RESEARCH, pretty please with a cherry on top.
This isn't a 'crazy' example of giant clouds, but this setup still had great flavour and the vapour production was really good. It was just a quick video I made for a thread on another forum.

The other way to get big clouds is build higher ohm micro coils (or any of the other crazy coils people are coming up with right now ) and run them on a regulated device at high voltages. This was something I was playing with today and the vapour production on it is great, and the flavour is still fantastic. It's 30g wire and about 10 wraps around the end of a really tiny screwdriver. This coil is really really small but it still puts out great vapour. But instead of being a really low resistance it's 2.5 ohms.

Anyways, it's late and I'm rambling, hopefully I gave you at least something to consider. Sorry for the lack of links etc to tons of info, maybe later if you need / want them.
