What is this about headaches, I never experienced a headache (6ft), sister rode it 6 times in a day (5ft 3), other sister must have done the same (erm... 5ft 9 :/), and not once has anyone complained of a headache or any rough section, I rode it last week for the first time and was expecting a really crap ride after all the reviews and was prepared for the worst, and I actually really enjoyed it, EXCEPTIONLY SMOOTH, only downer with me is the restraint tightened a bit more on the immelman, but it didn't really bother me until we waited to get off.
