Don't really have a suggestion I was debating whether or not to add the adapters and try cartomizers. My concern is how long they last. I drip because I hate fiddling with carts but. Dripping is inconvent unless I am home just wondering if caretomizer would be a better choice all around. So I too am intrested if anyone has information
You can't beat the convenience of the carto's. They're all I've used, since I started my ecig life with a KR808D-1 so as soon as I saw DaMulta using cartos on his Chuck, I went straight for the Chuck as my first mod.
As I have a Little Chuck, it's strictly 3.7v, and I'm not a chain vaper so your mileage may vary, but a new carto will last me about a day. I've been refilling my cartos for awhile, generally just topping them off every night, so I can't say exactly how long they last now--I try not to vape them down to the burnt taste and carry a couple with me for variety and in case I run one down.
Again, as the cartos are completely portable, it makes traveling with them a whole lot easier...just grab a spare battery, 3 or 4 carto's and I'm out the door. If one dries up, I just screw on another one and keep on vapin'

You completely avoid the whole "dripping, priming, refilling, dead atty, carrying another whole basic setup" situations with the cartos...
