I hope this is the right forum for my question. I need some suggestions for a new saddle. Unfortunately, I have some special needs when it comes to saddles. Years ago I had a spinal fusion (L5) and in order to get into an aero position, I have to rotate my hips forward - I cannot bend my back at all. In that position, my sit-bones do not touch the saddle - all my weight is on the pelvic bone. I can tolerate that, but I cannot tolerate the pressure on the "girly parts".

So the saddle must have
(1) a somewhat wide (~2 inch max) and flat padded nose to spread the pressure on the pelvic bone
(2) a flat surface overall
(3) a cutout to prevent the "girly parts" from being compressed
(4) a long rail so I can position the saddle as far forward as possible (I am very short waisted)

Any suggestions?
