Why do coasters which are the same model and constructed by the same manufacturer sometimes ride differently? surely a coaster with the same layout, same height, same trains, made of the same materials etc would ride the same! What factors could be at play? ....age? (obviously a 'newer' coaster would ride better?, climate? a coaster in a hotter or colder climate might somehow be affected by that?, paint job?, overall weight of all the passengers taking that particular ride? time of day? - we all know about a coaster 'warming up', where you sit - well all know about the differences a ride makes!
