I ride both saddles, the B67 breaks in easier and is a little more forgiving on your behind than the flyer. I also use the 'S' or short versions of these saddles, the Champion S and Flyer S models are shorter and slightly wider than the standard.

The specs I've seen put the Champion and Flyer at 172w X 175, and the Champion S and Flyer S at 177w x 245. The B67 is 210 x 260, B67S is 210 x 235.

If your riding style is more upright, I'd recommend the B67; if you are using drop bars and/or putting more weight on your hands, the Champion S or Flyer S might be the way to go.
