I've found a better, in my opinion, carto than the EMDCC. It's also a Smok, but it is the EMSCC at 1.7 ohms. It's shorter than the EMDCC, but holds just as much liquid. Works very well with VV. Find'em at Mad Vapes and Hoosierecigsupply. Be careful, as there is a clear version and a metal version. I've found out, the hard way, that the mouthpiece on the clear ones tend to get stuck in the carto and you have to pry them out. The black metal ones do not have that problem.
