It seems like when you use up the liquid around the coil, you need to rest a bit, and allow the fluid some time to soak the coil region again. Technically, I think that is what an atomizer bridge intended to do, but wicking juice through the batting to a bridge was more complicated and difficult.
Given time, however, the carto should have no problem with liquid SELF-redistribution. Many times, I hear that you should let them sit a little while even on the first fill ever. Time is what allows the entire batting to get moist, and well, basically what I'm posting is that I wonder if those for whom the new coil design doesn't seem to work good enough are possibly just not allowing a few minutes of time for the batting to self-resoak.
The area around the coil should be able to hold 4 to 8 drops, that should be long enough for one analog's worth of use duration, so relaxing a bit and allowing your carto to self-resoak itself may at least be helpful. I haven't tried these new ones yet, but from the sounds of it, I wonder if this could have something to do with it.
( If this makes sense, then it could almost be possible to burn any carto of any type by deliberate means. Simply vape like a maniac or even worse, have two people vape on the same carto like crazy, and I am almost willing to bet that you can easily burn any carto of any model and of any type, by severely vaping much, much faster than the batting can redistribute its juice. )
