The height is roughly 100-105ft iirc. I forget the exact height and it’s not published sooooo...This is not a very accurate height check but when I was in the park a few weeks ago it looked a few feet taller than Great White (the Batman invert clone) which stands at 108 feet so it definitely looked and felt bigger than invadr at 74 feet.
Pretty easy when the coasters they would have been competing with are now made of steelBased off the leak that basically nailed Pantheon from SEAS, they were shooting for a list of -est( longest, fastest, tallest, etc) in Texas for wooden coasters with this coaster. So it depends on if they are considering Iron Rattler a wooden or not. If they aren't then they would need to clear 96 feet according to RCDB
