So I've been using a folded ptb for filler and so far it's working great for the most part. I've had some flooding issues I don't quite understand and the carts seem to empty rather fast for a mid range vaper like myself. I'm using a joye 510 with a folded half piece of ptb, I can get 10 drops or so into it but it seems to flood at first no matter if I put 8 or 12 drops in (which I don't understand), and when I start to be able to taste the ptb over the flavor I can pull the ptb out and see that it's almost completely dry, which is great and all, but it seems to run out faster then most on the forums suggest theirs last. I'm curious if there are any tricks I may have missed or don't know about to help the ptb filler work better (until I get some supplies to be able to try out some other mods I've had my eye on) and hopefully flood less.
