Well in 1991, in my eyes and at my age looping coasters were it. I couldnt wait till March 23, 1991 It was my new #1 coaster (out of 6!). It was definitly smoother back then and when it opened it had 3-6 car trains. But soon after it opened they realized that 3 trains were impossible so they stuck an extra car on the back of each train to make 2-7 car trains. it also wasnt braked nearly as bad back then so maybe that has something to do with the roughness.
Thanks everybody, glad you liked them,
