Clones are often frowned upon among enthusiasts for basically offering the same layout as another coaster. Supposedly they're cheaper than an original layout design, but by how much? I've never seen an extensive research or analysis on the topic. A corollary question is how much work and energy does it save the manufacturer to go cloning? I suppose they still have to adapt some calculations to the new park's terrain if needed for example. Also, isn't a clone ride likely to be delivered more quickly to the park? Less time spent on coming out with a new design, and maybe the factory can work faster with a layout they're familiar with?
