If the SI Diva doesn't work out -- in addition to the Specialized saddles, some other t-shaped saddles are the Selle San Marco Aspide Glamour, which is very firm (not padded at all), and the Bontrager Affinity WSD. The widest Affinity is almost exactly the same size/shape as the Aspide Glamour, but it is available in 3 different levels of padding, with the RXL being firmest and the R being most padded.
Good luck!
