re: your MotD:
either Charon (biggest) or Obelisk (seems most popular) would seem the logical way to go
however, I have no idea of differences in mineral requirements, BPO prices and ship turnover, i.e. profitability and/or competition (last one meaning possible 0.01 isk annoyances when trying to sell)
also, I don't look forward to a redo of Fountain POS refueling. Aerie gave me an idea of the amount of minerals that are involved in the building of a freighter and I for one am not really (understatement) attracted to hauling millions of m3s of minerals from god knows where to god knows where. so what will be important, imho, is that some people are willing and responsible to pull this beast of a project. plus either some sort of wages need to be considered for ppl doing this project, or it might be an idea to have those ppl doing it semi-independent from corp, i.e. buying BPCs from KASEI for cheapish and keeping all hassle AND profit to themselves.
just my point of view
(havent seen any corpmails on it yet (saw it on Anga, didnt log Saf), so I might repeat someone else, but w.e.)
