Ninja at SFOG: Refit it with Carolina Cobra restraints to remove the main issue with the ride
Scream Machine at SFOG: retracking is in order, DO NOT alter the ride itself.
Mindbender at SFOG: stop saying it has 3 inversions in press material, and make the final brake run less sudden. (either way, this coaster is awesome!)
Georgia Cyclone: light it on fire, and when it is reduced to ashes, build a better coaster.
Hurler at Carowinds: Hurler 360, anyone? (yes, really.)
Carolina Cyclone: rename it Carolina Corkscrew
Expedition Everest: make the headrests less painful. (not vekoma levels of skull tenderization, but close)
