Although my favorite PV is the Triton system complete with their 2.4ml tanks, often while running around/work etc., I still prefer to use cartomizers for sheer convenience and shorter ecig. I have gone to the Halo LR cartomizers and am definitely pleased with the results. The LRs definitely provide a warmer/stronger vape, and while they should drain the battery a bit faster and the ejuice run out a bit faster, I haven't found it enough of a difference to worry about, and IMHO, the increased vaping pleasure is more than worth it. I don't have the G6, so can't comment on how they perform with the G6 battery, but I would expect a "larger" vape for a small form factor ecig. I really appreciate how Halo gives us a pretty wide range of solutions within their "ecosystem". Although I have no real issue with occasionally using some 3d party hardware, I prefer to stay with the Halo tanks/cartos/mini clearos, I have had consistent quality and performance from their gear.
