What does the fact that it was the last of it's kind have to do with removal issues?
And something bad happened on SoB, but that's still standing. Unless something real bad happens (De-Railing, e.c.t.) it should remain in operation. And who's saying something bad will happen? Every Arrow Suspended except Bat, XLR-8, and one in Japan are still operating. Bat was a prototype, XLR-8 went down with Astroworld, and the one in Japan had a rare accident.
