Well I started vaping around 2 year and recently I switch to a mech mod, now I'm confuse I've using a vgod mech mod with Sony vtc5a, and every time I go to vape shop they ask me "what coils do I have" I'm running single coils kanthal 24 at 0.17 I know I'm vaping on danger zone I'm clear on that but my question is this people always say you should run some dual coils at 0.30 they will give you great vapor production but the thing is if this is correct or you can't have a great vapor production with a 0.30 build also I'm Claud chaser. Thanks sorry my grammar sucks
