My ears were red for an hour after my last ride on Viper and my head was throbbing and I said never again... Granted, that was probably 6 or 8 years ago, but I have no desire to go back. The trim brakes also kill the whole back half of the ride for me.
Geez! I've never had an experience like that on Viper. Every time I go to the park, I end up going on viper twice in a row during night time because the line is always short at that time, and I actually quite enjoy that ride. Yeah, the ride is a little jerky at times, but I haven't really noticed any pain while riding. I guess that might be just me, as I'm one of the few who actually enjoy Green Lantern, and the bumpiness of Ghost Rider.
