Yesterday I did a bit of experimenting. I pulled my VPX tank apart, stuck a regular old 510 atomizer in it, and used the pointed engraving dremel bit to make a TINY hole, probably a 1/3 of a mm or smaller, in the side of the atty, right next to the bottom cap. I also had to dremel 1/8th inch off the tube to support the shorter length of the atomizer. I've been using it for almost a whole day with NO LEAKS, NO FLOODING. Just deep, flavorful hits every time, equal in flavor to dripping, and plooms of vapor.
I put a couple pics up here:

Perhaps this could be adapted to the Hybrid/Gummy tank idea? The trick to putting an atty inside a tank seems to be to make the hole small enough that it doesn't break the surface tension of the e-liquid, except when you take a puff.
