Ok, I finally took this out for a road ride, 25 miles on Huron River Drive, Ann Arbor to Dexter and back. First reaction was, this is still hard as a rock, but if I can float over the saddle enough maybe it worn't be so bad. So I soon noticed I was not easily able to float my body over the saddle, so I lowered the saddle a few mm. A little better. I also checked the screw to make sure it was in all the way.

Then I noticed pressure around the peri, so I started to slide the saddle forward bit by bit, and to lower the nose. The nose got to about 1/4" below the heel and saddle went forward about 15 to 20 mm. The pain reduced, and I began to feel normal pressure around the sitbones and less at the perineum. But now I felt abrasion on inside thighs, so I tightened the screw a few turns. This resulted in the pressure points leaving the thigh area and more focus on the sitbones, with no pain. But I was sliding forward in the saddle, but if I pushed back with my arms it was pretty much ok. Pain continued because I had already suffered some abrasion down under.

I decided to ride the 12 miles home from Dexter with the saddle as it was and actually it was not too bad. Next ride I'll experiment with raising teh nose to prevent sliding down the saddle, and perhaps slamming it forward a bit more. I also think I need, for the sake of science, to ditch the super-long Nitto S84 seatpost and go back to a normal setback job like an old Campy or a setback Thomson, or whatever is in the spares box. At this moment I don't need deep setback.

I think the NSX is a good experiment, and it might turn out to be a good saddle. It seems to be getting more supple, since it has a little more give when I flex it with my hands.
