Best Coils for Kangertech Subtank

What is the best coils to use when owning a Kangertech Subtank Mini. I personally have used the Kangertech vertical 0.5 OCC coils and have liked them however I am a heavy smoker and i tend to burn through the coils faster as opposed to if you had G Clapton OVC Coils that are also compatible with the Kangertech mods. Its all on preference. Call today if you want the best prices!
