If looper had stayed at Alton towers, would Rita have even been thought up? Two launch coasters that go the same speed would be a waste of good cash.
That says a lot about advances in technology, the launch speed of a new multimillion pound coaster with complicated hydraulics can be matched by dropping a big weight down a tall tower.
I miss thunderlooper dispite never having been on it, my first sight of it of the day always got me excited about being at alton towers, and it certainly looked impressive. By the time I was tall enough to ride it had gone (not that I'd have been brave enough at the time anyway!).
