Agree but Raptor at Cedarpoint is five years older and runs in a much harsher climate, although, as you said, it is closed five months each year. Even so, it runs very smoothly. I would also submit that not all B&M's react the same. Diamondback at Kings Island opened in 2009 and has developed an annoying vibration at the bottom of the hill exiting the hammerhead turnaround. In the back, it's a little rough. Other B&M's don't have that problem. I rode Hulk last year and thought that it was pretty smooth. So, it could just be the train that you are on or the seat that you are in.
