John Thanks. I will look into the twist and vivi nova the videos you posted were helpful as well. If I get the twist can I attach it to the
ego-t are these parts interchageable? Please give me a recommendation on where to buy the parts u mentioned. Cignot has the twist batteries that sure is cheaper that what I paid for the kit i purchased oh well.
BB, this situation is much rosier than it might look. Yep, ALL of the parts are going to be completely interchangeable. You can use the eGo-C atomizer with "B" tank on the Twist or on the constant-voltage eGo batteries that come in the kit, and same with the Vivi Nova, or just about any attachment that has the "510" connection that's on all eGo-class batteries and just about every device there is except some of the ciggie-sized PV's, where you get into standards like the "808" and (one or two?) others that I'm not so familiar with.
MORE good news: The eGo-C atomizer with "B" tank are still
cool, are an important (IMO) part of vaping history, and while not as well-performing as the Vivi Nova (or a host of other attachments out there, that I'd be happy to tell you about if you email me), it's just a neat setup to own. It's VERY "stealthy", the tanks are really neat (as in "neat-o"), a lot of people use them pretty much exclusively, and they can be tweaked to perform better than stock, as in this very long thread:

And again - compared to what you've been spending on smoking, what you're going to invest in this equipment is insignificant. Remember, it doesn't turn into butts and ashes, like cigarettes do. You get to keep it.

(Or lend it out to help other people stop smoking!)
Lastly: Just as a Twist can deliver the same actual vape as a ProVari, those constant-voltage eGo batteries you're getting can provide a perfectly fine vape as long as the "correct" resistance of attachment (atty, cartomizer, clearomizer ....) is used. "Correct" in quotes because the amount of watts you desire at the coil often changes because of different flavors of juice, variations of resistances between batches of attachments, worn-out taste buds, or your mood. That's why VV is such a no-brainer to me - especially since the Twist, and now the couple other eGo-class VV's - but the point is that CV can "get you down the road" pretty well.
Once you go back and forth between the Twist and the CV battery, I think you'll see what I mean by all this. In the meantime, just look forward to a good vape, and please don't feel as if you've "wasted" any money, because IMO you haven't.
Cheers, mate.
