Sorry, I don't own a V2, or have plans to own one, but I couldn't let this bit of misinformation pass...
An electrical Circuit is just that, a circuit. Every component of the circuit matters, whether it is before or after the desired load point in the circuit. If you put a resistor in front of the atty (positive side) or behind the atty (negative side), it has exactly the same effect on the the whole circuit, of which the aty is a component. Since the atty is a resistor, and the body is a resistor, at least a portion of your battery energy is going toward heating up the tube. Since stainless is not extremely resistive, and the circuit is overall low amperage, you lose battery life and deliverable current to the atomizer, but the tube doesn't even get warm to the touch.
Wow no offense but I was merely telling him that it wasn't stainless where he said it was... I must have gotten over zealous but i meant to say there is no stainless to effect current to the atty. And you are right when you say a circuit is a circuit but most of the juice is being "used" before it goes back through the stainless.
