To answer a few of the questions...

It's a 130mm saddle. My fitter did measure the width of my sit bones, so I'm guessing that should be correct. Just maybe a case of right size, wrong saddle?

I've never really had one I loved, but I've also never really shopped that hard for one before either. I've also never used one with a large cutout.

I don't know if my LBS lends/rents/etc. saddles, but since my bike is less than a week old, I'm guessing they will likely try to help somehow.

Thanks for the thread link. I will check that out.
