STmini UPDATE: So I've had STminis since their introduction and have tried to run them to death. I'm strictly an rba user as I've never been happy with the flavor production of the occ's. I've run kanthal, nichrome, nickel-200 and titanium-g1on the rbas and have had no problems making each build work flawlessly at 30w with 75vg juice. You just can't kill these things. They have never leaked, threads have not stripped out, glass has not broken even when dropped (ymmv), super easy to fill and they have sufficient airflow to chain vape up to 45w with 60vg juice without modifications.
For temp control the STmini is rock solid with no res fluctuations. A ti build in an STmini on an Evic VT60 temp control mod is an absolutely stellar vape; as close to dripper flavor as I've ever been with a tank.
I'm talking about V1 STminis here, the rbas with juice channels, not the newer "plus" rba version with holes that peeps are calling V2's. The V2's may work even better, don't know, but if any of you out there are on the fence about buying a rebuildable tank, take the plunge, I think you will be happy with the STmini.
