Ever consider that vivi novas just suck and cartos are better? Put a cart with the right resistance on a battery, be it cig-a-like or larger PV, you get the same thing as long as it is wet. 3.6 from a little battery works the same as on a big battery. Put a vivi on it, it sucks no matter what you use because they just can't wick well enough. You have to do the tilt and swirl business to even make it work well enough for one hit, much less consistent hits. I know people like them, but I just can't see why when they don't last long and can't deliver?
What the problem for me with the cig-a-likes are I got sick of charging them every hour. Consider each battery only lasts x amount of charges, you are basically paying all that money for less working time overall. I want the same hit, time after time, with as little fuss as possible. Get an RBA working right, you have it for days, even weeks sometimes with no tilt and swirl, no head changing or any other nonsense. Just refill.
Get rid of the clearos altogether, use the cartos (best in a tank) on whatever works for you. If you want a little more set up time, but a longer functioning unit with every hit, get the RBA.
In the end, if it makes you happy use it. If you can afford to buy up the little batteries and replace them often, go for it. I want one holder I can replace a $10 battery once a year, with a nice wick and coil I can tailor to my needs that will last a long time with no problems.
ETA: sorry if this offends, just drinking the wine after watching Walking Dead so I am a bit on edge
