As much as I like the Elite - and my other manual
batteries - I urge you to go with your
own preferences. There is no one best e-cig (or feature) for all vapers.
You might want to consider getting the cartomizers to use on your current batteries. For example, I'm enjoying vaping an Elite carto (with 510-to-808/901 adapter) on one of my 3.2V eGo batteries: provides a milder, smoother vape that is good for some juices and moods.
