so i got my provari and am using the dct v2 tank with the pre punched cartos and when i got my vari, i put a new carto into it (it was working great before on the ego and/or lavatube, but great is relative cuz the pv sucked... so yea) and it just tasted burnt and ....ty. i tried and tried ot get it to work and finally got ...... and ripped it out, tried using a saddle valve to punch a carto and put three small holes in it and it flooded a little but it was leaking because of the way the valve pushed in the sides of the carto... so bleh, i threw it out. took another one and cut slots into it, and it worked alright, i cut three small ones in it, and it worked decent for a day or two, then started flooding like crazy, but then actually just kind of stopped working... it would go from totally dry hits to floods
