The wheels definitely make a difference in how the ride feels. That said Outlaw Run at least began with steel wheels on topper track. I think that may have changed though. I say just view classifications differently and have "traditional" wooden and "non traditional" wooden coasters. I agree that topper track and for that matter plug and play aren't traditional wooden construction. But they have a lot of argument to be under wooden coaster classification.
I was browsing Youtube, looking for something to watch, and this came up. Could not find just a random thread for this I thought it would fit, so I just made this one. Thought it was a interesting look into the past of Kings Island, as it is a promo from the TV show "Entertainment Tonight" for the new-for-1987 Vortex.
I think it is very cool to see the coaster back in its very early days, when 6 inversions was the most in the world, and 148 feet was the tallest roller coaster in the world*. Still, 31 years (and MILLIONS upon MILLIONS of riders) later, Vortex remains a popular coaster at Kings Island. I even remember last year, the park (or someone in T-Shirt design at least) thought enough of it to put it on a "Kings Island 5" T-Shirt with Beast, Mystic Timbers, Diamondback, and Banshee.
*= Unless you count Dragon Mountain @ Marineland in Canada, which is 186 feet tall and opened in 1983 but also heavily used terrain to boost its height as it sits on a tall hill and does not have very tall supports due to this.
Funnel cake stand expansions, Starbucks moving buildings, and restroom remodels. These are just a few the non-Earth-shattering, not-completely-new-building-construction changes to the park that have been hyped on social media way before opening day. I'm not buying that they've simply built a new restaurant from the ground up without a peep, and are just letting people find out as they visit.
