And I don't much care for the Smok 1.7's! I think they are a bit airy and don't seem to feed my 50/50 mix well. I'm having to fill the carto at least once a day to keep it from tasting burnt. This is just my first one, the others may get better, they may not? I like them better than the 1.6 DC's I was using, but they fed well, just burned to hot, even turned down.
Like the other said, it's about finding what you like! Some like the Vivi's, some don't. Some like the RBA's, some don't. So far I like the tank carto's best, I just have to find the carto that suits my wants, but I may be into RBA's before that happens?
