I've been on the 200ft+ Star Flyer at Plopsaland, and that was good. But good is as far as that goes really.
I was really looking forward to it, and I shat myself, they are scary, if you're afraid of heights, avoid (I'm not afraid of heights, but I was nervous before hand)!
One thing I was surprised, with, which didn't help with me already shitting myself, was how small the chains were that hold you up, with no fail safe cable or wire for extra safety. I've got real boney fingers, yet the chain was still smaller!

I think seeing this before hand certainly made me feel better!


Couple of nice shots:


Needless to say, there aren't many people waving their arms about, or making any noise and sudden movements!
I forget the manufacturer, but I like them Star Flyer's, I think them Windseekers look crap and ugly, so it will be interesting to see what Zamperla come up with.
