So now that I've figured out how to have a consistently enjoyable vaping experience with the Aspire BDCs I'm curious what the difference is between vaping a 1.8 ohm vs a 2.1 ohm replacement head. I have an ego twist which as variable voltage from 3.2-4.8V. What difference in flavor/vapor/temperature would the different ohms make? Or does it even matter since I have a vv device?
