Hah, that is why I love my REO!You'll go thru more juice with an RBA. You'll also drain batteries faster with an RBA.
You'll get more vapor production with an RBA. My experience, I get just as good flavor production with a good carto in a tank as I do with an RBA. I get a more dependable and consistant vaping experience with a cartotank, so it is my staple delivery attachment. My experience with RBA's has been that they can be finicky and inconsistant, requiring frequent tinkering to keep them functioning optimally. YMMV.
I primarily use cartotanks, and use my RBA's only at home along with the cartotanks. I've had SS wicks last over a month, and coils last a couple of weeks or more with intermittant use. My wicks are pre-rolled and partially oxidized when purchased. Doing pulse dry burns when setting up the coil wrapped around the wick further oxidizes the wick where it needs it most.
I found my RBA's would leak if taken out of the house, so they became an at home device only. I enjoy my RBA's, but often do not want to take the time to tinker with them if mine are performing sub-par. Some vapors enjoy this aspect of vaping, I don't. My cartotanks are easier and maintanance free, so they are my mainstay.
That's my experience, and the experience of others will be different.
