Hi, I'm noob. I've got the Drag 2 kit. My unique tank is the Uforce T2. I'm vaping 3 diferente ejuices now. When I want to change of eliquid I have to clean the tank (I'm using a different coil to every ejuice). I'm considering to get another tank but I don't know if it would be more worth buying a RDA/RTA. If is better another tank, is better the same model or you advise me another one to probe? Thanks!
