I have to say (albeit possibly not something everyone would agree with) I really like Spinball- it's a lot more intense than it looks (perhaps more fun to ride than Th13teen which is good but not the best ride in the park) and I enjoy it as much as the SW coasters so I'd like it to stay.
I agree with those thinking 'water ride' for SW9 as this and flat rides are the biggest areas the park is lacking- it now only has the rapids which are from 1986 - the flume was even older (1981) - both remain(ed) great rides although the water on the flume was often a bit yuk looking- it was often rather murky compared to some other water rides.
So it is a long time since a new water ride at the park and they've never had a really world class one by current standards so with Air and Fire maybe water could join the line up 'the world's first coaster fusing coaster with water' he says tongue firmly in cheek
I can see this being something planned- with removing the flume it may even have been a possibility for SW8 but then they decided the time was right for wood. I think we will see a major water ride at some point soon even if not as an SW.
