My take on the E-Go C is what ever works for you. I have one and it has been flawless. I leave in the morning with 2 cigs and use about 1.5 of it before I go to bed. Does higher voltage and LR atomizers have a effect? Sure they do, but where does it stop? I am waiting to read about someone with a mod that they converted there hairdryer because it gives great TH. (don't try this at home) Ego is now coming out with a VV battery that will leave alot of other mfg. out of the picture. I for one will follow Joyetech
I hear what you're saying, somewhat, but having now had some experience with higher voltage (5V Smoktech Woo), I can now begin to fully understand the benefits of higher voltage vaping. It is a whole different animal, and you get a LOT more flavor out of juices when you can power the atomizer coils so they get hot enough to really get the juice motivated. With a full-range (3-6 volt) VV APV, you can dial them in to the exact right level for any particular juice, regardless of whether you're using single or dual coil.
(Very interesting thread here on single and dual coil, and how each one needs to be powered - I consider it a "must read").

Don't get me wrong, I'm not slamming Joyetech batteries - not hard, anyway. For what they are - a relatively high-drain, reliable 3.4V sealed battery - they're fine. But even with a low-resistance "works", 3.4 volts will simply not give you as much flavor and vapor production as say 5 volts. I know that for a fact because I'm doing it right now. Going back and forth between a 1.5 DCT (Smoktech 3.5ml tank) and a 1.5 EMDCC (jumbo cartomizer) first on the Joyetech and then on the 5V Woo, there is a world of difference. The flavor (my "Studio Reference" flavor, Geoff's Blend from Tasty Vapor) is far more muted on the Joyetech than on the Woo. At 5 volts, I can taste the sweetness on my tongue, the flavor is much fuller, and the vapor production is far better. If you think you can get this same performance with a 3.4V Joyetech battery, it's simply because you don't know what you're missing. I don't mean that to sound arrogant, I just think it's true. I didn't know what I was missing either until I experienced it for myself.
Yes, the Joyetech eGo Twist will make for a better vape, but it's still going to limit you to 4.8 volts, and that will be derived from a 3.4V battery, with the voltage transformed up. The Woo is a particularly powerful device because it has 2 - 3.7volt batteries = 7.4 volts that it regulates down. Much better battery life and current flow. The same is the case with the new Smoktech VMax [ProVari clone]; using two batteries, it will outperform the ProVari V2 in getting power to the "works"; electrons will simply flow out of it faster, like water flows faster out of a garden hose at higher pressure. Just that simple.
Using single coil stuff on lower voltage devices helps, since with a dual coil device each coil only gets half the current of a single coil at the same watts, but there's still no substitute for higher voltage.
Where does it stop? Well, I think it at least seriously slows down when you have a full-range VV device, like a ProVari V2, Provari Mini, Smoktech VMax, Lavatube, Darwin, or one of many others. I will probably always use my Joyetech with the eGo-C works that I'll soon be getting, but I am certainly not going to restrict my vaping to only it. It's great for out-and-about, and for looking relatively inconspicuous, but now that I know what a superior vape higher voltages give you, there is no sensible reason for me to use it 100% of the time, especially when I'm relaxing at home, and want the best vape I can get. No Joyetech battery, including the Twist, will provide that.
