I agree with kcies13-SFGAm, the Whizzer's rolling stock is cool. It's open, only a seat belt, and the inline seating is different, quite nice when with your girlfriend (or for you girls, I guess it would be boyfriend.)
Second best would be Apollo Chariot's and Raging Bull's, and I belive Nitro is also a B&M hyper, is it not? Those things rule, the big T-bar, which is easy to keep loose, the open sides, not front "wall" to the car, the confortable seats.
They would be the best, only it has B&M's (seems almost like it's trademarked) 4 across seating, which really limits vision in the center. It's not as bad on that coaster than on others, like thier inverteds. Those suck in the middle. Rode middle of Batman: The Ride once, never again. Only edges! BTW, front car on Batman=heaven!
