I bought a couple of tube tanks and packs of cartomizers from Volcano along with my Lavatube. I figured I'd use one of the tube tanks on the Provari I recently bought. Unfortunately I'm having some troubles with the carts. Reading through their forum, it seems to be a common problem. I see a lot of good comments about Boge carts, however. My question is, can I use them in my tube tank, in that are they all generally the same size? I know I may have to punch the holes myself- I'll probably pick up a saddle valve tomorrow. Or do I have to buy new tanks also? Right now the cartos are either running dry or flooding. It's as if there is some tiny window between not enough dry puffs, or too many. I managed to get the 3rd 3ohm carto working, and I'm about to try on my 3rd 1.5 ohm DCC.
