I'm probably not the best person to reply but doesn't seem like anyone else is. The amp tank is brand new not even out yet. Russ from click bang put out a video review of its function. Search amp tank to find his video. The thread is called something like amp tank amp tank amp tank. He has a link to his click bang episode that he goes into his experience with it so far. It sounds great and he prefers it over rbas it seems. (Don't want to speak for him)
I have been stalking avid vapor so I can get one as soon as they become available
I tried reworking the Vivi with ss mesh without much success and just gave up on it. Been using carto
tanks with ikenvapes fusion cartos for the last couple months and they are working great but I'm thinking the amp tank will replace these assuming I can grab one.
Hope you get some more people to weigh in here and help you more but since there are really only a couple people that have even used the amp tank it may be awhile till someone can really weigh in accurately.
Good luck and vape on!!
