Hi, I just bought a kayfun, I like building and I like not buying coils in atty's. I have amassed a good amount of juice at 12 mg which isn't working out for dripping. Will I have the same problem with the kayfun? Is there a build where I could be able to use up 12 mg then change coils then start the 3-6 mg stash? I'm working with a provari and an istick. Kayfun v3. Dripping using an omega for right now. Thank you!
