Hey all I've been vaping with my ego c twist for a few weeks now and feel its time to move up. I'm doing a lot of research but am trying to find out what my next step should be, and which unit people would feel is appropriate. I'd also like a unit that would be able to work with my kanger pro tank 2 because I don't want to replace it if unnecessary. Open to all suggestions and price isn't my biggest concern although I am not trying to break the bank.
