find pBusardo's you tube review video on the vivi nova and the protank. Recoiling and rewicking are done basically the same as the vivi nova but the wicks are cut shorter and there are 2 small top flavor wicks laid across. Once you see the vivi nova one and see a prtank head taken apart you will know what I am talking about.
Thank you, Myrany, that did help a lot. And thank you for the reference to pBusardo's videos! I've heard the name mentioned but this was the first time I checked out his videos. Amazing resource! Thanks again.
