That coaster is Cyclops. It is the strongest airtime wooden coaster I've been on. They have a rule where you must be 18 to ride back seat, but when I was there it was not enforced (thank god!)
For a steel coaster, back seat Demon @ SFGAm. That whips you out on the first drop. You slowly lift out, then whip out just as your barely off your seat, into the harness, and WHAM, back on your seat going through the loop.
