I'm 160 center to center. Bike shop told me I was 150 on their measurement. Went back to another guy - same machine and he told me 155. So take their measurements with a grain of salt.

12 saddles later (or more, I lost count) I think I found my friend. Selle Italia Lady Gel Flow.

160 with a nice cut out. The Diva didn't work for me (155). The Terry Liberator (160) is almost the same as the Lady, but it's super puffy. And heavy. The Lady is not as thick and fits me quite well.

REI carries them and will allow you to return it even used.

Me + Brooks = not going to work. Plus, I don't like the weight of the Brooks. Too heavy for me.
