tsunami i hear is a nice one.. how do you like it?
Depends on your vape style but i would have to say you would go through more e liquid in a tank than a dripper .. a lot depends on the power/temp and of course the tank itself.
cool cool... but what power settings ... coil size ... someone that likes 50 watts will def go through more juice than someone using 25 / 30 watts all things being equal.. larger coils can use more juice as well .. but if you were to keep everything the same from dripper to tank i'd still say the tank would go through a bit more.. chimney size and air draw variations will also make a difference .. smaller chimney will concentrate flavor and perhaps not use as much liquid to produce the same flavor. It's really a 'how high is up?" type of question
hmm well more juice = more flavor - sort of - lots of opinions .. everyone has their own style etc.. MTL vs DTL for instance.. MTL tends to be more flavorful... taste buds are in the mouth after all .. some of the best flavor I get came from aero mini tank with a1.8ohm coil.. I think that that thing held like 1.5 ml of juice .. and would last most of the day (at least half) soo 320F seems a cooler vape .. with 4mm coils (btw they are just coils .. micro is anything around 2mm) are you getting a lot of spit back or un vaporized juice coming through? With 4 mm coils you would use more wick than with say 2.5 / 3 / 3.5 (larger diameter needs more cotton) so would use more juice to feed the larger coil ..
what is your concern here .. are you looking to economize on the amount of juice you use?
