Baditude has a blog with an overview of different systems. It's not up to date as far as the current hot toys (Protank, EVOD, etc.), but has good basic info:
Is it a carto? atty? clearo?
Awesome, I'll check that out. Basically I've been using mini nova's on a ego twist for about 6 months now, and haven't really looked into anything else. However, I recently upgraded to the Evic and I'm looking for a bit better delivery system for it.
It seems carto
tanks are good (but I'm a bit cautious about potential slippage-leakage if the carto moves). The new protank, iclear 30, etc have me interested as well.
I have tried a kanger t3, but not on the evic. The problem I had on the twist was flooding, I like 70/30 or 80/20 pg heavy liquid.
My biggest complaint about the vivi's would I guess be a tight draw and the fuss of cleaning the heads every day or two (I do have a lot of them so I save them up, but I still spend an hour or two a week on it). I'm considering rebuilding instead, as I think it would actually be less time and trouble than cleaning them, by my procedures.
So I guess my wish list would be a nice airy draw, little to no potential for leaks, and ability to get a nice warm vape with lots of vapor production. Is that asking too much?
