^Plus, Phantom's Revenge was almost a complete revamp. The only remaining components of the original coaster are the lift hill and the train chassises (chasses?). All the rest of the track was replaced with brand new track, thus minimizing the amount of retrofitting that Morgan had to do. They didn't just replace various pieces here and there.
True. I was quite disappointed with Goliath's drop the first time I rode it. Twisted Colossus's drop is honestly scarier, IMO. Even though it's only half the height of Goliath, the steepness makes all the difference.
