I just rebuilt my Magma clone with a 1.5 ohm single coil build with Kanthal A-1 28 GA. I formerly had a 2.3 ohm coil with kanthal a1 it had way more surface area but it also took longer to heat. the 1.5 ohm coil heats almost instantly and put off a way bigger plume of vapor. i used the same juice as before and the flavor is way better as well. I lined up the ring to the middle air hole and so far it works great !! I wonder what a single coil 1 ohm build would be like seeing how I can only go down to .9 ohms this things rocks now the Magma its putting out huge flavor I originally had it set at 15 watts I had to turn it down to 13 it was putting to much off and I was getting a slight burnt flavor . I am wondering what other builds would be good for me . I cant seem to figure out a good double coil configuration that will put off a real good amount of vapor maybe the MVP20 W does nt have the balls to heat two coils but it should if I build it right ? Right? What should I do about the double coil it should put off double the vapor and flavor any suggestions would be greatly appreciated Remi Love
