Can you change juices in these tanks as you would with a PT? Seeing your comment made me wonder if it is possible to change juices in the tank without having to break it down and wash it to get the old juice out before adding a new flavor.
coils taking time to "break in" and swapping flavors in a tank arent really a common thread ...
sometimes the coils present a smoother experience after they aquire a slight coating ...
switching eliquid flavors in the tank to get the pure characteristics of the new juice without blending with old eliquid often requires the tank and wick mat'l be purged of old flavor by rinsing or dry burning or switching out wick ...
as far as the ceramic wick mat'l of the bvc...it retains the flavor for varying amounts of time depending on the flavor characteristics of each eliquid...
light fruity vapes are covered up quickly by heavy tobaccos , for instance
while other flavors seem to blend out nicely...
the old pro tank heads would take to a rinse and quick dry burn, so do the bvc's, you just have to use caution and not be too zealous with the bvc's...
bottom line...try vaping through the liquid in the head, worst case, its not the best taste, but doable...
or rinse and shake out head and vape through the new water diluted flavor, or
rinse, carefully pulse dry burn, and you are off...
play around a bit, find what works for you, have fun and dont let the tank/heads intimidate you
