It depends what type of seats they use on the PTCs...the hard foam ones kind of hurt but the upholstered ones (which Dash has) are great. Parks go for the hard foam ones because they don't tear...but they aren't really comfortable at all unfortunately.
Anyone been on the Coney Island Cyclone lately? The padding they have on the seats and lapbars is ridiculous. It's like instead of replacing track on the ride, they add more padding to the seats.
