When filling a carto place a round toothpick in the center hole to keep the juice in the filler material. This prevents the juice from flowing thru the center of the cart and being wasted. This works well for topping off the cartos.

Atomizer Mizer
Now I'm confused. If you plug the air canal that the liquid would go through with a toothpick when using the condom method, then how would the liquid get into the cartomizer stuffing? It makes sense to me to stick the toothpick into the inner whole of the carto after removing the two plastic peices on the mouth end, and then dripping liquid in via the mouth end. This way, the liquid would go directly into the stuffing, without any liquid getting into the air canal.
