+1 - make sure you demo different saddles!
For those of you measuring at home, keep in mind that your sit bone width <> saddle width. if I recall correctly, the specialized guy measured my sit bones at 135mm, which put me between the 143 and 155 widths for saddles. Maybe specialized has a table on line somewhere, I'm not sure.
I tried a 143 Toupe and hated it... immediately. I tried a 155 romin evo and still love it. There are not many saddles out there for racing bikes that are wider than 143, though.
Is the regular romin a different shape? The Evo has *slightly* more padding but I'm not aware of any other differences.
