i recently bought the horizon arco sub ohm tank and put it on my g-priv. both coils that come with the tank are 0.2 ohm coils. the first time i screwed it on the mod it read around .34. the second time it read .27. i know that i can manually set the ohms on my g-priv by setting it in TC mode whether i vape in tc or not. i was curious is it safe/recommended to manually set my ohms to .2 ohms since that's what the coils are rated at? i'm not sure if the 510 is shorting out or something but vaping a .2 at .27 or .34 seems like it would damage the coil quicker in my opinion. any recommendations?
