Lets be honest, Liseberg, more than any other park, seems to have a very brutal aproach towards ditching old rides in favour of new ones. Give it ten years and I wouldn't be surprised to see Balder scrapped in favour of the "next big thing"...
Second only to Phantasialand.
Liseberg are far more brutal. When Phantasialand remove a ride, it usually makes perfect sense. It's an aging ride that looks dated alongside the park's newest offerings. When Liseberg remove a ride, it's a case of "What!? Didn't they just build that? But there was nothing wrong with it!"
Have we seen B&M 'go back' to traditional restraints after introducing vests on that model? I was shocked to see them on Hulk but they haven't put them on a sit-down/floorless yet, i don't thinkWith that final inversion I reckon vest restraints are on the cards.
