Welcome to ECF!
There's a lot to get into. I'd definitely recommend spending some time reading the various things so you can get a better idea of what you want to get into. You can look into mods, which will give you a pleasant experience above your current VV devices. There's pretty much endless combinations of tanks out there to try, too. There's RBA's and RDA's, but that's definitely not something for beginners...but to hear the people here say it, it's the best thing. These forums are chock full of information on the
vaping scene, you could spend years here, no doubt.
I think the goal should be to find what works for you...there's a lot of people here who pursue gear endlessly and I see no reason for that. That could be your current setup, it could be something ultra-advanced. Part of it, though, is looking at your vaping style, looking for gear that fits that style and pulling the trigger to see how it works...then you'll truly enjoy that "next best thing" for you!
