Standard Resistance? Low Resistance? Single Coil? Dual Coil? Boge? Smoktech? I've shopped around and tried a few, and I know it depends on what your device is at, but this is confusing. What do people out there use? I use ego batteries right now, which I believe are at 3.4 volts? and I have my first mod on it's way to me from ecigworkshop.com. I got the Twig that is powered by a single 18350 battery. I'm also interested in getting a tank for it, and I have no idea what to get.
