Hi, I was thinking about buying the Kanger 1.2 ohm enclosed wick but am not sure exactly what wattage or voltage to use. I currently use the Protank 3 on my istick 50w. I am currently using the 1.5 ohm wicks and run my device at 9.2 watts and 3.8 volts. So I was wondering if this is right and if I should up the wattage for the 1.2 ohm coils and leave the voltage the same?
