Store I bought the Selle Italia Diva said I could try it out. It's too small. If it was wider I think it might work. Looks like it only comes in a 153 via Selle's website. It's a gorgeous saddle and hate to return it, but thankfully I can send it back. Talk about awesome customer service from this company even though I went through Amazon.com. Guy has a nice online selection of stuff so hopefully I can use his store for other purchases.

Thanks for all the advice. Even if the Lithia doesn't work out in the long run, I know what I'm looking for now.
