im looking to blow huge clouds and im new to sub ohm/mod vaping. I have a kangertech sub ohm plus tank but the prepackaged .5 ohm coil can only go up to 30 joules. i want something that can function at 50w/j but be able to go up to at least 100w/j. im willing to spend up to $60 for something. also, if you suggest an RDA also suggest what type of build with wire gauge and all the info please.
