I have dripped for years using 901s, and never used a cartomizer until last week when I ordered a couple of tanks from IBTanked. Personally I feel that the flavor is muted compared to dripping, but I love the convenience. I ordered a Vivi Nova that should be here in a few days, and am researching the Drunker rebuildable as well.
I ordered a bunch of flanged cartomizers, but they won't work with my Precise 18650 without an extender, which I have been resistant to use. I also got some unflanged cartomizers, and punched them myself - and as a result have had a horrible time filling the tanks - even using the tank refilling drip tips that came with my tanks. This culminated in my spilling THREE tanks full of liquid all over myself and my desk today, and me about to scream in frustration.
When I got home I broke down and pulled out the 510 extender, and used a flanged, pre-punched cartomizer. It made all the difference in the world. No more pushing the cartomizer in too far, or pushing the end caps off. I don't like the look of the cartomizer on the extender, but I can live with it until the Precise ELA that I preordered comes.
I'm still waiting for the Nova to come so I can try that out (I ordered some aluminum tubes as well) but I am going to bed much happier with my tanks than I was this morning.
As far as flavor goes, it still doesn't seem as strong as dripping, but I am glad not to be dealing with the - oops too dry, shoot I flooded it, where is my bottle, hassle.
I'm waiting for Valleyvapes to get their Pyrex Sidewinder tanks back in stock - that looks even easier than a regular tank with a flanged cartomizer.
