From what I saw at the Wallingford site, the B72 is the same width, but without the same springs.
Of all the wide ones, which fit on "modern" seat posts? I didn't understand the single rail/double rail stuff.
And do the women's versions really make a big difference?
Are the springs the greatest thing ever, or can you skip the springs and still be happy?
Jeez, I guess I'd better go over the the Brooks thread. Betcha all my questions are answered over there.
