Im waiting on my Changeling by Olympus creations, its due to be here Monday. I only have one rda and 2 RTAs, im looking for a high end copper rda for super low ohms. I own an atomic and i absolutely love it, but i don't like that it is not 22mm and i want a copper rda to match my changeling. I really love the way the copper Quesar looks and ive heard good things, but i love the Mephisto by el diablo as well, it has the largest post holes ive seen, a deep well, and great airflow. my favorite builds are either dual twisted 28g or dual vertical coils at 24g, it is close to immpossible to build these in my atomic so the mephisto seems perfect but the Quesar could be even better anyone have both or even one and have any advice?
