Son of Beast during opening year, before any of the support structure was reinforced, was absolutely brutal. The rose bowl was the most unpleasant experience I've ever had on a ride. That's the only time I've ever found a ride so painful that I couldn't find any enjoyment. If crushing spines is cool, then consider Son of Beast Miles Davis.
I rode it again in 2003, and it was actually pretty tolerable. A completely unrecognizable experience from my first ride. It seems all of the structural reinforcement really did improve the ride experience, even if the engineering was less than adequate.
