Provari + ibtank + Ikenvape pre-punched cartos = heaven. A bit finicky but once you get it dialed it's fantastic. I also use a Vivi Nova, which suffers in flavor delivery but excels in reliability. It just always works and never leaks.
Finally getting around to researching all these suggestions. Thanks, by the way.
Which cartos are you referring to from Ikenvape? It looks like they have several different models to choose from.
