I have been using a Bella carto tank for a year 2.8 ohm at 4.8v to 5.1v. I have just got two orchid RTA's. One is a VOX and a v4. I am new to building coils and need all the help I can get. I get my best flavor a 2.8 ohm with catro's. Would I get good flavor at a different ohm and wire. What size wire should I get and what ohm should I try? I have 3 iSticks, 2 EVic and 2 EverCools. Do I need a different mod?
