They are all different types of wire and have different properties.
I hate to point out the obvious, (to me at least) fact that a single battery mod is probably not the BEST first option for "huge gigantic clouds," even if you had the best battery in the world in there.
If I were you, I'd buy a regulated dual or even triple battery build and some drop in coils as honestly starting OUT with an RTA/RBA well man, IDK.
If you must do this, well check out steam-engine.org, look up or ask about the stuff that doesn't make sense (a lot of it will not make sense) and well, hang out in the rebuildable section of the forum and etc. If you are mechanically adept and whatnot yeah, watching a few you tube builds on your atomizer may help you. Etc.
I still think you have entirely the wrong gear but well maybe your definition of cloudy is different than mine.
Best of luck, welcome aboard.
