Just picked up the Magma and to take advantage of the deep well, I decided to use a single coil so all that wick would not take up
juice space, but I also wanted some heat behind it. That left one choice, a 26g parallel coil on a .095" gauge pin, 5 wrap and .33ohm later and she is cooking. Instant action, tremendous flavor and great smoke output.
I tried the build I had on my Stillaire, which was a 5 wrap dual (open) coil on a 6-32 screw with the 26g and the Magma produced a 'brighter' flavor with lots more high tones. The juice was Darth Vapor which is a rich tobacco flavor so maybe not the best juice for the Magma, but still very good. Think I prefer that juice on the dual coil Stillaire though...
