I'll go first... RTA, 26650 form factor/size. (28 to 30mm wide) With interchangeable 22MM build decks. Single, dual, triple, and quad. With proper wick channels to support each. Interchaneable chimney sizes, from 12MM chuff style to 4mm standard kayfun size. Fully adjustable massive airflow of course. Juice flow control/shut off and top fill. I figured if you make the tank size 26650, you could make the build deck 18650 sized, allowing you to have "true RDA performance" in a tank. As long as you have the airflow and wicking capability to support it. What do you all think? Let's hear some more ideas...
