Can't find any Oxva .3 ohm unicoils.Wife favors the Oxva Origin mod with the disposable Unicoils in .3 ohm. Every site I've been to is out of stock including Oxva. Do they stop making them so you have to buy the latest greatest system? No aftermarket support seems to be the norm. I have a few RBA's for the tank but she doesn't care for the hit they give. Any help, ideas or suggestions for a suitable setup that compares?
