I've been struggling with wicking Subtank occ coils but just can't seem to get it right. Often, though not always, I can reach around 25w, but never the 30w I could with the stock .5 ohm coil. I've tried different builds, around .7 with 26 ga kanthal, from 1-1.8 with 28 ga (all spaced coils). I've tried different wicking styles, a little cotton (muji pads), a lot of cotton, leaving a short tail outside the coil housing, cutting the cotton as close to the liquid holes and tucking into the housing. Nothing seems to work. I've watched plenty of rebuild videos on youtube and it feels like I've tried everything.
You who've successfully rebuilt/rewicked the occ coils, could you please offer some advice?
