Thanks everyone for your replies. They have given me lots to think about.
I decided it made sense to try a Specialized saddle, since they're so easily available at local shops and they are pretty t-shaped. I bought a Lithia, in 145 mm since that's what the measuring tool recommended. I chose the Lithia because it was more t-shaped than the Jett and supposedly is designed for a more upright position. I looked at one of the mountain bike saddles that Muirenn mentioned, but it was very hard so I don't think I would like it.
The store offered a 14-day return period, but due to lousy weather and being busy at work, I was not able to test it until day 15. So, anyone want to buy a 145 mm Lithia? Because it was very painful. I'm inclined to think the 155 mm version would not be good either, because I think pressure from the edge of the cutout caused problems.
My LBS bike fitter is in Belgium right now for the Tour of Flanders (lucky him!!). Once he gets back, I will make an appointment to verify that my position on the bike does not need to be changed. And I will probably try the Affinity next, although I will feel really guilty if I buy and return yet another saddle at his store.
In the meantime, I'm thinking of putting the Evoke back on the bike temporarily, so I can think more about what I do and don't like about it. I was able to do shorter rides on it last year without pain, and I can't say that about some of the saddles I've tried lately.
If the Affinity doesn't work, I'll look into the SLR Lady Gel Flow and/or Diva, as well as Brooks.
BTW, I saw an SI Turbomatic at the LBS last weekend. It is very firm.
Thanks again!!!
