Just wanted to toss this out there...I am in vamping bliss!!! My little feeder is kind of based on puffs 901/MAP mod. I started thinking, we have the liquinator, which requires a cut in the side of the carto, but I hate cartos, I also hate CE2's. So 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 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.
That being said, I don't know about this being considered a Provape Feeder, because I am sure they could come up with something better, but I would LOVE to see a Provape tank, caps made of stainless steel, bottom cap made to match the Provaris endcap, and top cap made to match the Provari's top cap. I think it would look gorgeous...
