Between me and my gf, we both have a normal Ego-t, I an Ego Twist, and she an Ego C upgrade. WE use vision 2.0 clearomizers. We normally use 2.4ohm atomizers, but when trying to buy replacement wicks only 2.8ohms were available. Is it best to use the 2.8ohm atomizers with the Ego C upgrade and Twist? Im not exactly sure what the best battery voltage is, and i know that less resistance will probably require higher voltage. I know that my Twist can go up to 4.8volts and the C upgrade has as high as 4.2. i think the Ego t only uses 3.7 volts. So should we try to stick to the C upgrade and Twist while using 2.8ohms ? What are peoples experience vaping between 3.2 and 3.7vs with 2.8ohms? thanks for any help
