Kinda feel like most everything you said right there was hearsay. Superman never got reprofiled, just new trains and started running backwards. When it first opened it was one of the most covered roller coasters in the world because 400 feet/100mph was unheard of back then. The issues started when SFMM got cheap and stopped running it at full speed.
I'm still surprised that I305 doesn't have a longer wait time for KD, it's certainly not the MF homerun in terms of popularity but still a great ride.
Although I'm not a fan of Kingda Ka, I disagree with this list. I305 does, indeed, intimidate many people, but it was still sporting some long lines during Haunt this year.
