I'm the same as you Adz.
I've been on a few, mostly not liking them a lot, but my favourite- by far- is Tower of Terror. I don't know what it is about it, but it's much less intense, and the acceleration is much lower. Great dark ride as well- although the song is scary :-\. One of the funniest things ever was, as the ride cycle changes, instead of being launched up at the start, I dropped down. It scared me *%&*less, but it was a great laugh.
When I went Phantasialand, I didn't experience Mystery Castle, and I instantly regretted it, it sound like an incredible experience to me. Maybe, one day in the future, I'll visit again and ride it.
