Look up viper at SFMM. its 188 ft. tall and has a 171 foot drop. And its a arrow multi-looper(7 inversions to be exact). Last remaining of the 7 looping trio of SIx Flags and the tallest of the three. Its nearly 200 ft. And it can go upsidedown 7 times!. Son of Beast was 200 ft tall and the loop was sucsessful(it wasnt the problem of the ride)So that proves an inversion can be done on a 200ft rollercoaster(hypercoaster)
