Which glycol system should i run?

[Cosmos]

Alright, here is my situation, i am planning on changing my entire bar setup in my pub and install a massive long draw system. The system will be around 75 feet long and run with 24 beers on tap. I figure the best way for me to accomplish this will be running two 16 hose lines, giving me 12 beer lines and 4 glycol lines a piece. Now my question is, should i run two smaller glycol packs with two pumps a piece, or should i run one large system with 4.

One 250 ft. unit with two pumps will do the trick, one pump for each 12 product trunkline.

One 250' unit w/two pumps would do the job or another stategy would be to use two 125's with one pump each (one pump will circulate a 75' twelve product conduit). If one unit went down, the other would still allow for dispensing.
