But height requirement is not the sole determination of whether a person will ride it or not. You mentioned that Joker, El Diablo and Zum have only 48" requirement, but neither my wife or I have ridden those three, nor will we ever. We also won't ride this new Cyborg next year. My wife used to ride Rolling Thunder but will never ride El Toro. I rode El Toro once and that was enough for me. Same with Green Lantern. The only coasters my wife will ride is Skull, Dark Knight and Harley Quinn. She won't even ride Runaway Train because it is so rough now.
