Right now, I have a 1.2 ohm sigle coil setup on my IGO-W attached to my K100. I redrilled one hole to 1/16 and covered the second hole with JB Weld. I love the hits, gives me a good amount of vapor, and i like it. What's the deal with everyone doing a dual coil to quad coil setup running under 1 ohm? Doesn't it burn too hot? Kill your batteries faster? eat up ejuice like crazy? not sure what the big deal is with it. Maybe someone can open my eyes a little more..... Throw some knowledge this way please.
