Yup, i've been on pretty much all of the slides that I see at VB, leave out the Water Coaster as I feel that will be fairly unique to other water coasters. Obviously the slides are custom to what Universal wanted, but they're still all pretty much all things i've been on.
What separates VB from other parks is that the collection of slides is all within the same park, making it one of, if not the best collection of slides at a water park in the United States at the very least.
