@godofporn thank you so much for your opinion.It's definitely how RTA decks should be done as a option for sub ohm tanks. Unlike some other decks which are shite
it is better to establish double coil,but users can try to build single coil(notice:block the other two e-juice holes with cotton)I actually found this searching yesterday, but there appears to be no option for a single coil if you so wished unlike some velocity style decks.
