I think it's the rider. I have never been on a 'violent' coaster. I want to get beat up, but in the late 70's people wouldn't ride the Corkscrew at CP because of the head banging of the shoulder harness. I thought they were insane, but that's them. People have different tolerances for rides, thus it's up to the individual. Mean Streak is perfectly rough, like a good woodie should be, but my thighs are bruised for a week after a ride on the Magnum, but hell, I don't care. It's up to the rider.

There's nothing like a woodie...
