Hi President, Welcome to the ECF. I would suggest you go your own way on this one. If you are eyeing the eVic, go for it. But for the love of all that is modded, please reconsider screwing an eGo-c atomizer on there. They are great for beginners, at low voltage, but they are troublesome for the most part and would not allow you to use most of the higher output settings on the eVic. The eGo"tanks" have the tendency to leak or burn one or the other or both(I don't even know how its possible but I have seen it first hand) and be very position dependent and inconsistent in general.
I would advise you to get yourself some eVod clearomizers, a Vision Vivi Nova, a package of standard cartomizers and give them all a thorough test run. All of the above mentioned feed systems are much easier to use, will last as long or longer than an eGo atomizer average lifespan and will give you wide range adjustment capabilities and will run circles around every eGo"tank" atomizer I have ever used. All that and these are less expensive to keep running in the long term.
