I use the Vapeonly 3.5ml BCC mega with 1.8ohm head, remove one wick and turn the silicone grommet upside down and this thing works amazing with the eVic. I have it set between 3.3 and 3.5 volts and there is tons of Vapor and tons of flavour. As a starting point I would try it with all the wicks in but the silicone cap needs to be turned upside down. It just allows the
juice easier access to the wicks. I also use the Protank and a Vivi Nova. I prefer the Vapeonly personally and it also looks amazing on the eVic.
