I think you might have to think a bit outside the box when it comes to saddles. I don’t know if you have tried a noiseless saddle. I have to admit, I would have to be in considerable pain to place one on my bike, but I would if it was the difference between riding and not riding.
79pmooney has also mention a 2 bolt seatpost more than once, even gave a good recommendation with a Suntour XC Pro. I’m not suffering with pain, but I picked up one of those seatposts and I love being able to fine tuning the tilt.
