So ive been vaping for the better part of a year but I have no real vapers around me. My batt is an ego t 1100 what ohms should I use to maximize me vape. ive been using a 1.8 recently went to a 1.5 on me mini protank 3 and me evod 2. I figure when the juice starts turning dark its time to replace me coil. cleaning tips would be helpful too
