It will be the same. I go through about 3ml per day no matter if its just carto or a carto tank.
Just my .02$ here, but the Smoktech Tanks and their cartos are just plain bad IMO. I tried them before going to Pyrex Tanks (glass). Pyrex tanks do cost a little bit more, but the quality is better hands down. And i punch my own Boge/Fusion cartos for those tanks. The carto punches are cheap and easy to use. They do not flood or gurggle or give me any issues at all.
Cheers and welcome to ECF
