Because if you have problems with one pack then only 1/2 your flight pack is affected. I think your Ultimate will fly nice on 8S. You can also split the packs for a smaller plane project too. Well even at 9S you can split them to 4 and 5 for some other smaller project.

As for capacity, I will go with no less than 3,700 mAh. Preferably 4,500 mAh to 5,000 mAh. The motor will be pulling about 50A-60A on 8S. I fly my Midwest CAP 232 on 10S and 5,000 mAh packs. I get a nice 8 mins flight using about 4,000 mAh. I fly her for scale aerobatics, no unlimited verticals.
