So I have been using an 510 atty for the last week and am loving it. Have only used 808 cartos before now. My problem is when I put the atty away and go out I like to use the cartos but notice a pretty big difference in vapor production and TH. Using 3.7 with 2.0 510's. I think the cartomizers are 2.5. All I wanna do now is drip. Is my problem with the cartos the ohm resistance?
