FWIW, I tried the "mini-version" at Six Flags Great Adventure in Jackson, NJ this summer (a friend gets free passes), and as I have a healthy fear of heights, I decided to conquer my fear and give it a try. Glad I did. Not as high as SP, but high enough to work with. View up at the top fairly decent, and the ride down was like 2 seconds. So I did it again. Next year (should we go) I'm definitely doing SP.
