I had a Selle Italia Turbo also and it was good for about 40 miles. I concluded I needed a wider saddle and migrated to Specialized saddles which come in various widths for the same model and have the cutout. I like wide under the sit bones but narrow at the front - sort of T shaped. I've lost a bit of weight and found I needed to readjust saddle tilt. I'm amazed how minute changes effect comfort
