The Jokers have the three fins along the top like Arashi, I think that Batman at Fiesta Texas is the only one now that has just the one fin at the beginning. But, I'd bet that the pushes forward from the fins are electric / electronic and the park can control how much a car should be flipped as it goes over them. S&S even says that a park can make the experience more or less extreme if they so choose and that the change can be made easily.
Obviously, Nagashima Spa Land went for the more extreme route. I think I'll be staying away from that one.
