I've been going back and forth between using: (2 stir sticks w/BP plug) (one straw w/BP plug) (BP plug alone) (BP full length wick) and (2 stir sticks w/white Fluval). The best vapor I've achieved so far in all those variations was, by far, the 2 stir sticks w/white Fluval - BUT - that could simply be due to unintentional imprecisions in cutting, stuffing, etc. the materials. I haven't yet found the sweet spot to keep my plug from falling into the atty during vaping, except with the Fluval -- again, I suspect that has more to do with chancing upon a best fit while using that particular material.
I do find that, indeed, the BP vapes to a dry finish. Not a drop left on it. Wow.
Has anyone else tried to roll a slice of BP to achieve proper compression? I had hoped that by rolling a thin slice of BP like a carpet, with the spiraled ends up/down, that action might allow the BP material to spring against the walls of the cart snugly and sufficiently without becoming too compressed to allow juice to flow. Sadly, as I've attempted this maneuver, I've mostly managed to ball the whole thing up so that it becomes a bit of a wadded mess,

so I can't report on the actual success of this idea. Anyone else give that a go? Any success?
