Well in my opinion it's still pretty intense, and it took me years to actually get the courage to ride it!
The worst part is going up. Just listen closely for the countdown so you know when it's going to drop! I love Detonator a lot, but I hate/love the feeling you get on it when you're falling. It seems to last for ever and it feels like you're just falling faster and faster. Great ride though, but if you're like me and you get a bit nervous about drop towers, it's an unexpected rush! You should definitely give it a go
