Diagram anywhere of air flow...

through a cartridge? Or is it as simple as whatever hits the atomizer vaporizes, what doesn't...doesn't.

I'm trying to figure out a mod to alleviate the "bone dry at the atomizer end but still wet elsewhere" syndrome.

There is airflow around a cartridge, but not through a cartridge. Juice is transferred by 'wicking' action when the cart filler comes in contact with the meshy material of the atomizer bridge. If the affinity of the smoking liquid to cling to the spun poly filling is greater than the wicking action, juice remains in the filling. Your vaping habits can also have an effect on wicking. I find that a heavy vaping session does not allow juice enough time to wick to the atomizer bridge leaving the end very dry, very quickly.

The whole process is generally pretty simple, yet elegant. I would guess experimenting with alternative cart filling material would be a better way to go.

Putting a small length of tubing such as from a cut Q-tip (cotton bud stick) into the edge of the cart helps by allowing air to get to the bottom of the cart as juice is drawn out.

Cut ends at an angle.

Not arguing with ya, just offering an opposing view and adding $0.02 Just to be clear, forums are funny like that sometimes.

Personally I think the opposite, the entire e-cig assembly is an engineering nightmare. Totally inefficient use of energy and way overcomplicated. I found nothing elegant about it.
