Temper, Temper folks!
I think Captain Robau was pretty cool, for the record...
I just think the ship didn't conform to pre-timewarp events. Everything after 2233/4 was changed... but stuff PRIOR to 2233/4 was the same right?
Then how could the ship be bigger than the Constitution Class which was supposed to be the biggest ship?
While Gene Roddenberry is dead, all the way until Nemesis, you didn't see rocket like exhaust shoot out the backs of the warp-nacelles...
And the reason why I state that the ship could not separate was because if they could, you'd figure in these circumstances they probably would! Plus the whole idea of twin-hulls was so that they could separate the primary hull as a lifeboat.
