Recently got into sub ohm dripping . Started with an Imortalizer at 0.9 and loved the flavor but it was too tight of a draw . The wife liked the the flavor and draw , so I lost my Brass Chi You clone , batteries , and imortalizer to her . Decided to pick up a MKB-TS #2067 and a Storm rda . Fixed the hot button issue with a copper shim , built a 0.89 ohm coil and away I went. It was a good vape , but needed more .......air . Tore it down and built a single wire duel vertical coil at 0.58 ohms and with the Storm fully open it hit great , if a little warm for my preference . Picked up a 1 inch tall 1/2 inch diameter stainless big bore tip ( a standard drip tip will fit inside the big bore with room to spare ) and just about blew the back of my head off . The vape is immense in volume and flavor with a perfect temp .
