I run mainly the Chibi tank from Parkes with Boge LR's, Smok DCC 1.5's & single 1.7's, with my preference being for the DCC's. I also use the Acorn tanks though I'm not a huge CE2 fan. I have a Tank Cartomizer from MadVapes on a DCC as well - it's a little prettier than the Chibi's but that $5 difference goes a long way in more juice, and the performance is the same. I'd even argue that while neither leak per se, the seal on the Chibi's is much tighter, meaning I'm more confident pocketing it versus MadVapes' model.
