I currently use either a CE3 or 2.0 ohm cartomizer with my twist and want to try out a tankomizer. My thought was that I would just get a single coil tank since my normal cartos are single coil and work just fine. I would think that the benefit of the dual coil would be for more vapor and throat hit, but does it also drain the battery faster? Shopping around, it seems like most companies aren't even offering the smoketech single coils systems anymore. Thoughts?
