I vote Battlecruiser all the way!! Involving the fleeters in the ship's design and construction is one thing, but having their officers and engineers working aboard his prized vessel is a non-starter!!! Would their presence be permanent, or just temporary?? As for the Battlecruiser's lack of expensive hull plating, between Gloriana's growing expertise on Archetech and Ves' grasp of the Darkness element, it might be possible to turn it into a giant stealth ship!
