Hey Sharon, I'm also sorta new to the ecig scene and I can tell you my experience to date: My first setup (after using those "disposable" models) has been straight to a cartomizer with a
tank. They worked well, but was getting tired of burt/gunked up cartos and not having the extended flavor you get when you hit the "sweet spot" with those (if ever!). Then I was turned on to atomizers which provided great flavor all the time, but dripping every few draws was starting to get old. I recently purchased a Phoenix RBA and I couldn't be happier with it. I'm having so much fun trying to wrap the "perfect coil" and I can get 7-10 hits before I need to drip again. If you are always on the go a
tank system is probably best. I still use an Artemas tank (on a Spinnner too!) when I run out, but not nearly as much as I've been using this RBA. If you're feeling adventurous, I'd would recommend an RBA.
Also, you need to keep in mind that some coils and their wicking material is more sensitive than others. I found
this chart in where the "best vape" is depending on your configuration. I know, sometimes you want an extra kick and feel like you should twist up the V's, but it takes a toll and before you know it you're having a bad vape.
Although I've leaned quite a bit from these boards, nothing beats having real-world experience of your own. Exact setups may give a different vape experience for different people so you have to experiment and see what you like best! Good luck!
