I think Flight Deck and Time Warp really need to go. They are rough, outdated, and not class-competitve for what they are. I would replace these with a top of the line inverted (ex. a Raptor or an Afterburn), or a winged coaster (being the new fad). The other option could be some sort of a high-speed launched Intamin (ex. an Xcelerator or a Maverick). Now that Wonderland finally has a record-class ride in Leviathan, I would love to see Cedar Fair focus on improving the depth of the park.
