I'm not sure I would really call the Golden Horse Wild Mouse models a "rip-off" per se, there are already at least six companies (besides Golden Horse) that make Wild Mouse-like coasters, and that's just from this page
. There are surely others that are not called "Wild Mouse", like Reverchon and Fabbri. So that's eight. Unless they're all ripping off each other, I don't think it's fair to single out Golden Horse and accuse them on this one. The SLC lookalikes, though, that's pretty idiosyncratic.
