Not sure, Riversurf; check out our
Seatpost Article for some ideas; one person mentioned a Suntour NCX. Are you not able to drop the post height enough to make your Thudbuster work? Any suspension post with this design will raise the saddle height some but if you could lower the post once you sit on the saddle, it might work. Also if you have a very "poofy" saddle, you might consider a thinner topped one, you might not need so much padding with a Thudbuster or Suntour NCX.
