Well, after I just bragged about how much I absolutely love this combo, I ran into a problem. I noticed the positive post on the ViVi protruded extremely far, so I filed it down. Apparently I did not file it enough. The first thing I used on my Ego-T Upgrade was a LR Resurrector Cartomizer, and while that was completely awesome I prefer using a tank. Ever since that first cartomizer I haven't used anything but a ViVi Nova tank. Well, I wanted to try a new juice my wife was raving about I just grabbed her carto and screwed it on. I found it would not fire. So I tried a whole bunch of different cartos and atties to no avail. It appears that the ViVi Nova Tank has compressed the positive connection on my Joyetech Control Head to the point that nothing else will come in contact with it. Now I don't mind using my ViVi Tank all the time, I was a little bummed to find out that I had NO choice but to use it. Time to buy a new control head I guess. Just thought I would mention this wondering if anyone has ran into this problem, or maybe, just maybe, I can help someone else prevent it.
Cheers.
