I did a kind of pictoral dictionary of common vaping attachments to use on your battery device here:

All these devices are a little different in how they provide flavor, throat hit, and vapor production. Everyone has their own opinion of which ones work best for them. The only way to know if one is best for you or not is to try them all out.
Many people believe that the best flavor comes from dripping juice directly into an atomizer. A few drops of juice is dropped into the atomizer or drip tip and vaped for a few minutes. The process is repeated over and over. I never cared for this myself as one must carry a bottle of juice where ever you wish to vape. I also could never perfect vaping this way, your results may vary. This may be what you were referring to earlier, or it could have been a cartomizer.
For myself, I get the most flavor from using a cartotank. This is a cartomizer filled with e-juice and has at least one hole in it. It is inserted into a reservoir tank and that is filled with more e-juice. These can hold enough juice to last a day or more. I'm assumiing this is what you have been using.
The Vivi Nova tanks work a little differently than a cartotank. Instead of polyfill in a metal tube (cartomizer), these use string wicks to draw the juice into the atomizer head which contains the heating coil. These are extremely easy to fill with juice, just screw the top off and fill. However, from my personal experience, the flavor is muted with some juices. Your results may vary.
