Thanks for all the replies. In no particular order, here are my responses:

- I did go through all the saddle threads before I posted here. I took notes as I read along and listed the Selle San Marco Aspide Glamour FX, the Selle Italia Diva Gel, and the Bontrager Inform RXL as possible candidates. I was hoping to maybe add more to my list, or delete one or more, so as to minimize the expense of ordering/testing/returning saddles. (There are a few bike shops in town, but they don't carry much in the way of women's gear - I'll have to get any new saddle online.)

- As I mentioned in the original posting, I do have my current saddle pushed as far forward as possible. The main reason is to have my knees directly over the BB spindle. I've had several knee surgeries and this position is the only one that prevents extreme knee pain (i.e., I have to spin as opposed to mashing the pedals). In addition, I have a short stem (80mm) to accommodate my short torso.

- The suggestion of the Adamo/ triathalon saddle led me to a web page that mentioned that tri saddles have more supportive and better padded noses - that sounds like what I need! I'll have to investigate these saddles further. Thanks for referring this class of saddle to me, I don't recall any mention of these in the forum's saddle threads and I was unaware of they existed.
