I've gotten into this somewhat disgusting habit of refreshing cartomizers with similar flavors. For instance, I start with a coffee flavor carto, and when it begins to dry out, I'll add a chocolate, vanilla, caramel or other compatible flavor. It's a variation on my "Dirty Atty" game, found elsewhere in this section.
Currently, I'm using a carto that once contained V4L's Ry4, to which I have added KBV OMG. When that's gone, I don't know what I'll add, probably a more neutral
tobacco flavor.
I'm trying to see how long I can use this one carto before it either gets cloggy and nasty or I burn out the atomizer in it BTW, here's a hint for carto users: If your carto is getting hard to hit, check to make sure that the center airflow channel is open and clear. This can be done by holding the carto up to the light and just looking down the barrel. If it's still hard to hit, I switch from my usual KR808D-1 to a 5 volt pass
thru; the extra heat often cleans things out, and incidentally will produce a fog bank of vapor!
Well, time to rummage
through the stash. This carto is getting a wee bit dry. Wish me luck!.
