Need help finding an equivalent saddle

So, I supplemented my 8 year old Secteur with a shiny new Diverge. Love the bike but the saddle is just a bit too hard on my aging posterior.

Now, I used to have this problem with my Secteur, till I replaced my saddle with a "Specialized Sonoma 105" - it's flatter than the usual road saddle with just a bit of padding and it's absolutely great - but they've apparently discontinued it so I can't buy a second one for my Diverge.

Can anyone help me find something equivalent?
