Wolf,
The juice would get vaped dry with the design im talking about. I disagree a bit with you on the taste thing as well, to me the taste is exceptional out of a carto compared to an Atty. A carto also last for a long time and they are much cheaper than an Atty to make because its mostly filler with a coil wire, and the wire would wrap around the filler the way I would build it instead of just going straigh up the middle of the carto the way they do now. The resistance could also be made to whatever one would like so they could be made @ 1.5, 3, 4.2, 5 so people could vape at there sweet spot, I prefer around 3ohms at 6v myself but others like different temps. I wont post a design because im chatting with Imeo on this and have been for some time now. Also Wolf my friend there would be no juice in the mouth ever with Imeocarto and thats a big plus.
