After getting a fitting the other day I realized that even when I have my optimal fit on a bike my sit bones are such that I slide forward (test - hands on the hoods then I let go...I slide forward a bit...granted much better than before since the fitting. This isn't a show-stopper as I can live with the situation without much discomfort, but the quest goes on...
My current saddle is curved towards the middle, as a result my sit bones are on the part that angles down. I can only tilt up the nose of the seat so high to get this part flat, therefore, I would like to get a flat saddle. I like the cut-out in my existing saddle, and I also like the liberal amount of padding (Terry Liberator Race).
So I'm investigating which saddles are flat, have a cut-out, and have liberal padding. The Selle Italia Flite Gel Flow seat that was on the fit bike was flat and had a cut-out, though I found it a little too firm for me. Granted, I wasn't riding in real conditions. Not sure if it after being broken in it would hurt after 2-3 hours in the saddle (though I may end up dropping some $ to find out).
