Okay, how do you hot swap a flanged carto in a full tank? I already lost half a tank of juice getting rid of the last bad carto. Boge F16 V2's. Considering that I only have one out of three that I've tried that works, I'm going to avoid using these from now on. Still, they're the only XL cartos I have at the moment, and I just got myself a very nice, Cirrus, custom tank in purple and black with rhinestones on it. A girl's got to accessorize after all. I love this tank, but I need to find me some better cartos for it. I love the juice in the tank, and it's the last of it! The Standard's Dead Man's Party. I was sooo looking forward to this, and I'm so disappointed. I have maybe enough juice left to prime one more carto, but I can't afford to loose what's in the tank. I've got an IBTanked carto fill tool if that helps, but I don't see how I'm not going to loose another tank full of juice.
