I don't wanna scare anyone off here, but I don't think you can compare BTMRR with Everest. Everest is FAR more intense. BTMRR at it's fastest goes about 33 MPH. Everest goes about 50MPH. What makes Everest so intense is unlike many other coasters, when it goes uphill, it doesn't slow down. That combined with the backwards portion, can make it very disorienting for people.
