The most air I've had was SROS at SFA, but the most Powerful I would say has to be the DB Hurricane - the bucking bronco of coasters. I'm a city-dweller, but that threw me back and forth tremendously so that's how I think of that "NON-FLOATER-type air". I wanna ride it right now, but it's a 6-hr drive...
