that blue fish aquarium filter stuff in cartridges (anyone remember those?) and then tossing the cartridge in favor of dripping (which I totally sucked at!!)
.
That blue stuff was before my time, but I did try dripping in an atomizer. No matter how hard I tried to mentally calibrate the process, I would always either not drip enough or, more commonly, flood the thing and end up with juice all over my eGo. After that I went back to cartos, where I started, and even tried the eGo-c system for awhile.
Didn't have a successful drip until I went with the igo-l, which basically opened the door for mods and other rebuildables.
