As of this moment, I'm rocking a 1.7-1.8 ohm carto in a 3.5mL DCT at 4V. It's perfect. I can rock it at 4.2 if I want just a bit more TH, but I generally wouldn't go above 4.2.
Enjoy the Twist. If you're planning to use DCTs with cartos that don't have the little wing at the end, like the smoktek cartos, then just be careful about sliding the tank to far is it may slide over the threading. A little screw on sleeve takes care of that though, plus it looks a bit more aesthetically appealing.
