In several posts, there's been a question about the different colors for supports, and I wonder if they might be trying to have them match existing rides near the Diamondback layout. If I have my bearings right as to what part of the park it's in, it probably goes near the Vortex at some point, and that has orange as part of its color scheme. I've only been to KI once, way back in '91. At that time, the railroad went from the theme park to the water park, but I don't know if it's been changed since then. If it's still the same, and those last Diamondback airtime hills go over it, then I think the larger hills, including the lift, would be near the Vortex. The videos probably don't show all of the existing rides near Diamondback, and I'm sure if they tried to show another massive coaster right beside it, the file size would be a lot bigger. Those Arrow supports would probably slow most of our graphics cards way down!
Of course, I'm referring to the Vortex as a "massive" coaster in a relative sense, because it probably set several records - height, speed, number of inversions, etc. - when it was built. I sort of hope the Diamondback lift isn't right next to it, because that would almost make it look like a kiddie coaster! Oh well, I guess worse things than that have happened to some of the other Arrow mega-loopers!
