I like big tanks and I cannot lie, lol I've read many posts that contradict each other about flavor in RDA vs RTA and what is MTL and all the others? Anyone have a link to an explanation of all these different options? I want something that doesnt leak so it sounds like the newer top air RTA's is what I need. The new WOTOFO Serpent Elevate looks pretty sweet. Do I want single coil, Dual coil??? What mesh do I use? What cotton do I use? What other items do I need to get started? Who has the best prices? How often do I need to rebuild? I've been using a Plato Aspire 1.8ohm for about 3 years now but have moved on to sub in a search for more, different and just started DIY juices as well So I just got a WOTOFO Flux Mod with RIg Mod Pro Flow tank using .18ohm mesh coils so I guess I need a 25mm RTA, maybe 30 if it has a bigger tank but I dont want it sticking out too much. I'm thinking something more along the lines of .5-.75 ohm running around 25 watts is what I am looking for but I could be dead wrong. Just trying to figure this stuff out!!! Thanks a BUNCH!!!!
