I'm just using an eGo-T with a tank/atty. It does what I need so I don't get to fancy with the hardware (i have enough trouble with keeping up with laptop hardware)
Though i do want to get a few different clearomizers that i've seen. They look promising for flavor quick changes.
As to the flavor I vap, right now its Desert Ship. But i've bought the chemistry set (lots of different flavors) that will hopefully yield a combination that gives me back my camel Izmir Stingers. Once I figure out the black magic behind that flavor i will be ordering it by the gallon and never worry about it again
