I already have an Igo-L clone and I've played with dual
coils on it, but I want something with dual negative posts. I honestly don't think $30 is bad for a fully titanium atomizer though. Titanium isn't cheap and someone has to be the guinea pig right?

Maybe I will pick up both the T and the W. Does anyone have experience using a single coil with dual airholes? Is it way too airy?
