Could someone please tell me what range of coils I can use in my isub g running on a coolfire 4. Is there higher ohm I can get to save on liquid and battery use whilst at work ? Also will the clapton bvc coils work on it as well ? Where can I buy them online ? I have bought some off amazon but they seem to be fake. The air hole on the 2.0 ohm one is small and feel like a really tight draw. Thanks.
