I'm riding a Specialized Lithia saddle now which is pretty T-shaped. It comes in three widths (130, 143, 155) like a lot of their women's saddles.

They have several different saddles that are pretty much the same shape, but different levels of firmness. The Lithia is a little squishy for me and I think I'm going to a Jett next time. If you've read on here about people complaining about the seams on the Jett, I guess Specialized was listening, because the '09 Jett has a lot fewer seams.

For an even wider T-shaped saddle, there are a lot of people here who just adore their Brooks saddles, and if you need a cut-out there's the Selle An-Atomica which is basically a Brooks with a cut-out.
