Always had a soft spot for Colossus, love the area and has always had one of my favorite pieces of theme park music.
I do agree though, it definitely doesn't have the same reputation of the likes of Nemesis or Vampire and can imagine when that time comes they'll be better off looking at something else.
But yeah, just interesting what happened with the re-track project as the need to re-track would still be there, but would be an odd choice to repaint the whole coaster if they needed to re-track it.
An Intamin multi launch could be a potential good replacement that could work without destroying the pathway when that time comes 👀
