Because I'm not sure what is meant by "RMC".
Rocky Mountain Construction (RMC) have made a name for themselves in converting old wooden roller coasters into shiny new hybrid roller coasters. There's a running joke that when you have a roller coaster of any type lying around that you don't want any more, just get RMC in to fix it.
If you haven't seen, this is one of their biggest conversions.
Never going to happen to Spinball though.
Perhaps you could squeeze a Raptor in there, but I suspect the neighbours might complain about the noise.
