I've played with just about everything out there except bottom coil clearomizers, and I
have always come back to cartomisers. Gennys are one of the best for flavor and I have to
compare the same flavor, side by side in a genny and a carto, to tell the carto is slightly
muted. Now for the obligatory caveat;
Cartos always taste best when they have just been filled. Besides capacity, that is one of
the main points of a carto tank, it is supposed to keep the carto at that just filled level of
juicy goodness. But tanks add one more variable on top of all the other variables of juice
and equipment, when it comes to performance, the weather and/or environment.
I use smoktech, SC, 3ohm, 2 or 3 hole cartos, and I make 2 of the holes slightly larger.
When the flavor starts to be muted, I do a few "dry pulls" until I get a hint of moist flavor.
That hint of flavor from a dry pull tells me the carto is moist again, and full flavor is back
when I vape. Obviously, too many dry pulls and the carto floods.
Now, for those who are not familiar with the mechanics of a carto tank, a carto tank works
because of a fine balance between the vapor lock inside the tank and the juice trying to wick
out through the filler via surface tension. Not enough vapor lock and the juice floods out through
the carto, too much vapor lock and you have to repeatedly do dry pulls to keep the carto wet.
I have a couple tanks that are loose on the carto and I have seen bubbles come up from
the bottom o-ring instead of through the punched holes in the carto. These tanks are more prone
to flooding if I do too many dry pulls.
I strongly believe that the environment ( altitude and barometric pressure ) strongly effects how
well the balance in a carto tank works, and this is why some people get so frustrated with carto
tanks flooding or the carto not staying wet enough to taste good and produce vapor. Their
environment makes it more difficult to come up with a working setup.
I don't know what variables you could change to combat lower pressures causing more flooding.
I know my problem is high pressures. I live at sea level and have atypically high barometric
pressures because of weather fronts moving back and forth across the coast. I keep my tanks
mostly full, and when I am out and about or working, and the levels start to get low, I will slide
the tank up and break the vapor lock ( equalizes pressure inside the tank ). Otherwise, I notice
I have to do more dry pulls to keep the carto wet. It seems like that may be part of your problem
as well. You might want to back off your voltage as well.
All this being said, no matter what juice delivery system you want to name, I guarantee you'll
find one person that says it is the greatest thing since sliced bread and another that will say it isn't
worth a plug nickel. Just remember, Experiment Experiment Experiment.
FWIW- I tend to use only the factory punched ( laser cut ) cartos, slots will tear up o-rings before
their time, and hand punched will deform the carto and compress the filler around the dimple.
Though, IKV cartos do seem to get a lot of good reviews.
