Just a theory I could use some input on: When using 100% VG liquids, wouldn't the added surface area of the dual coil cartos heat the juice more quickly and evenly across the filler, rather than cooking a single spot dry with each pull? If so, then perhaps the VG would wick more consistently with less waiting between hits, and it may also prevent the filler from clogging as fast or giving off that wonderful burnt taste we love so much early in a carto's life.
Again, just a theory. Any thoughts?
