when it says Resistance 2.2ohm(Mfg Rated). so can I not go lower? If I do will it burn the thing up.I have a lot of these and already, and like them for trying out new juices. but my istick 30 will only go down to 5watts. and if I can, can any suggest a coil that would fit this. I would like 1.5 to 1.8ohm. could I possible even rebuid it to a lower ohms. appreciate any help.
