Even though Detonator is (loosely) in Angry Birds Land, it still is a great thrill ride and really does pack a punch. The drop on it is very good; I found it better than Apocalypse at Drayton, which is almost twice as tall. Whilst taller drop towers have the intimidation factor, Detonator has the edge of being able to provide a better ride experience.
There's also the problem that Thorpe at restricted in how tall they can go, which would make a ride like Falcon's Fury more difficult to achieve.
