another Atomic report, page-5

Bear in mind that the Redfern site will no doubt have 12 or more different taps available... ~4 existing GR lines (not counting the original Atomic as one of those at this point), ~4 existing Matso's lines plus what?

I'd suggest that leaves room for at least 4 different 'Atomic' lines, as 12 - 16 would be my target number in a large venue... (As a comparison, BeerFarm are a WA venue that run all their own beers brewed on site out of what appears to be a 6 vat setup, and while they have 8 beers listed on their board, but I'm sure they actually have around 12 on tap at any one time)
