Personally, I found Power Dive painful yet still a good ride. But I also know it has had problems in the past. When I was their in May, some friends of mine got stuck in the restraints for 10+ minutes after the ride was over. What's worse, is as they were sitting there waiting to get off, the restraints tightened. If you've ever ridden Power Dive, you know how heavy those restraints are and, like me, can imagine how much it would've stunk to be them.
I agree with JoNoJ27, rides like Triple Play and Troika are my favorite non-coaster rides, and just about the only spinning ride I go on regularly. If anybody could tell me the generic name for this type of ride I would much appreciate it. Thanks in advance.
