Now that the problematic Superman: Tower of Power is long gone, the park is in need of a new drop tower ride. I think a Zamperla Z-Max would fit nicely in the former Xcalibur location and offer a different ride experience from the last drop tower. Six Flags Fiesta Texas is adding a small Zamperla Z-Max for 2024, but I would like to see a taller tower built at Six Flags St. Louis.
