Without this turning into what seat is best where kinda thing, as Gamfan stated above, for Viper/RB, those are prob. the best airtime spots (RB is a definate). However, on Superman, the back slams you into your seat on the pretzel loop. I can't handle it and feel a bit queezy when I go through it (as I do on spinny rides). If this is something like what happens to you, I would suggest getting as far up as possible. I ususally ride in row 2 as the front row has a long wait and row 2 is hidden within the crowds.
