I started out with an ego-c setup and recently stepped up to the ce5 clearomizer because of the ego tips leaking so much. Then I joined this forum and saw so many people raving about the vivi nova that I ordered one (still waiting). That being said, my friend told me today that the cartomizer tanks use less juice than the nova and performed better. I haven't tried the nova yet but I have noticed the ce5 uses way more juice and seems to be the same system basically as the nova. So here's my question. Does the cartomizer tank use less fluid? Are the vapor and taste better? Worse? If the carto is better, can you suggest an attractive (chrome) version, as the smoktech one seems to have black rubber caps? Thanks in advance for the help/advice.
