We've got the biggest and baddest setup in today. The Smok GX350 and the Smok TFV12! 350W capable and we've tested it to 300W so far. All we can say is "wow." Just when you thought things were at the peak with the TFV8, Smok went and proved us all wrong. The flavour starts to come in around 100W but it gets better the higher you go. Even at 300W, the vape is warm but certainly not hot. The flavour is wildly intense and the ramp up is very quick. We have yet to try the other coils, but so far, the V12-T12 are just awesome. The air holes are just massive, as you can see from the picture and it is perfect for the amount of power it takes. This is definitely is a step up from the TFV8 for anyone that can handle big airflow and tons of vapour.
