Try 0.8 ~ 1.0 ohms at 4v ( though i have no clue how evic works) A mech mod always does it better. That'll hit better. Technically, the bigger the air hole, the better the vapor production is. And since you're on VG, the vapor should be massive.
If it still isn't, then it's all on the wick. Too many variables.
I have a feeling its in the wick and I'm not having much luck with making the wick small enough to fit in the coil I made. Any tips on rolling the wick?
