I think the cone is part of the atty on those? Not sure.
Something else you may want to add for dripping - 1-2 510 atomizers and a 510 drip tip. And many plastic and delrin 510 drip tips will also fit in the Boge cartos as a cool mouthpiece that is easy to remove for adding eliquid. I recommend not putting untested juices in cartos since cartos have limited lives. Some manage to clean and dry them them fro more use. I just keep mine damp and get usualy 10 days use out of one, then I start another.
What PG/VG did you get in that juice? Tanks like 30% VG or less but may work okay with some 50/50's. In the cartomizers I prefer 20% VG or less - soaks in quickly, wicks well. I also avoid any juices that seem to drop a lot of flavoring sediment (clogs cartos).
