I use the LR Smoktech Dual Coil cartos, but I feel like I lose some juice. I love the cartos, but it takes a bunch of juice to make the initial fill, and I don't feel that I get that juice "back". Once they are full I have to top off again a few hours later. After that they are great and I usually only top off once a day. I almost feel like I should presoak them with something. Am I alone here or do any of you feel the same?
