Quickly, while the subject of a giga looper has been brought up:
While I've been sort of disenchanted with looping rides as of late, the thought of a 200+ foot vertical loop has always intrigued me. Inversions were fun when I was younger, especially when B&M started coming out with all their rides in the early 90's, and I was like, "Ooooo.... what's this zero-g thing all about, that looks fun... and this diving loop, that's fun too...", but it sort of faded for me after a while. That being said, the first time I rode Superman at Fiesta Texas, I was taken aback by the hangtime at the top of the loop, and was sort of smitten all over again. Heck, I ride Mr. Freeze multiple times every year, and going backwards through the top hat still makes me chuckle.
Just wanted to pause and think about REALLY big inversions for a second.... k, got it all out of me. Carry on.
