So maybe I went too far in saying it lost its touch LOL. I'm not trying to complain or act as though the ride is horrible or something.. I'm sure it was just the wheels like someone said before. Diamondback is one of the smoothest rollercoasters that I've ever ridden. I was just commenting that this past time I rode it just felt rackety and I've never experienced that before. I always sit in the back and never a problem. But oh well, its still the best at Kings Island, so I can't complain much. Vortex..now thats another story LOL. And Mean Streak at Cedar Point is a headache waiting to happen.
