Seconding Zippers, such an old school and intense experience. Speaking of old school, I got to ride a Roll o Plane for the first time recently at Knoebels and that was super fun too, and surprisingly intense.
I think Screaming Swings in general would be my 2nd favorite. I’m just always annoyed by how short the ride cycles are!
Just looked up a video of the Turbo and what the hell… That is diabolical lol
