Oh, yeah...lift that bottom! I rode it once last May, and noticed that the rollers banged your bottom a bit as you were going up the inclines . . .but I couldn't move or shift b/c I was holding on desperately! (Anyone have any recommendations. . .before "takeoff" the CM told me to settle down further in the ring)
That night at the hotel as I was toweling off, I noticed huge (about 3 inches across) purple bruises on my bottom...didn't hurt too much-just looked awful!
Ride is fun, though. I didn't flip at the bottom, but several did. One of the shoots is supposed to be the tamest (I think that it's the one farthest to the right when you are on the platform)--I think it's "coconut."
My seven year old rode it.
