I ride a Fizik Vesta.

I tried moving the saddle forward today so I was more on my sit bones even in an aero position but after 4 hours of riding, decided I def need a cutout.

I love the generous cutout on the Selle SMP but I've tried 3 that didn't work. I will try another next week.

You are probably right that I need more of a t-shapped saddle but I'm so bad at distinguishing between a pear and a T. how can you tell the difference. Do you know if the SI SLR Lady is a T? That is the next saddle on tap to try out.
