I did some research, and found that Cheetah Chase at Holiday World's Splashin Safari goes 20 mph fast and Kings Island says that River Racers will go 30 mph. Usually the speed is actually less than advertised at first because of weight distribution and all that. In regards to height of drop, I found that Wildebeest at Splashin Safari has a drop of 38 ft, while Kings Island says River Racers will have a 33 ft drop. In height, Wildebeest is 64 ft while River Racers is 48 ft. I couldn't find if any of Krakatau's stats at Volcano Bay, but it might break some records. In regards to how steep the drop is, I think River Racers is steepest.
However you put it, you can always say it breaks records:
"Tallest, Fastest, Steepest, Longest, Water Coaster in Ohio" (which is the only one is Ohio)
It doesn't really matter what records it breaks, as long as the slide is fun. Can't wait to get on it this summer!!!
