Many of my friends are also scared of the ride because it looks quite daunting. The ride experience I would say isn't as scary as it looks but it is still one of my favourite rides because of the unique experience it gives.
Slammer and Rush are the only different flat rides at the park, the others you can get at lots of places so there is nothing really special about them. I hope Slammer does manage to open again and not have the amount of problems that it has had recently.
