My personal thoughts are the vivi nova is easy to fill because of the twist off top and they do produce a lot of vapor, but they sometimes lack in providing full flavor with some juices. I base this on side by side comparisons with the same
juice and the same APV with a cartotank.
My favorite
tank for my Provari is the
IBTanked - Get Tanked With Us! pyrex cartomizer
tanks. I currently have seven of these in my collection from multiple tank vendors. I did a review of these tanks here:

The slimmer 19mm tanks fit perfectly on top of a Provari size wise. Prices start @ $20 for the tube and acrylic caps; stainless steel caps are also available for a little more. The standard size tank uses a 35mm carto, the longer size uses a 45mm carto. Pre-punched cartos and drip tips are available on the site.
I prefer using pre-punched cartomizers that use a 2.5-3.0 ohm resistance for the Provari. My favorite is the Ikenvape Platinum Punched! I'm experiencing full flavor with these, and they seem to be lasting at least an additional tank refill of juice compared to the Smoktek cartos I was using previously.
