i quit smoking mid January of this year and I started vaping a Fe w months before that. I have tried other methods to quit, nothing worked before vaping. I love it and I will never go back. I have found that I love rebuildables. I'm sure like most vapors I keep buying stuff and progressing. My question is what high end RTA's do you recommend? I also have mainly used single coil 24 awg titanium wire, temp control.
