Had a Ti Airborne Post on my Ti Airborne Lucky Strike. (Replaced a Roox S4) It did take the edge off trail buzz, but (and it’s a big but) I do not think it’s sufficient to warrant buying a new post on that alone.
It simply makes so little difference you may be better off getting a more suitable frame, suspension post or even bike if you really suffer that badly. Even a saddle change can make as much difference as the post.
Jumping off the Airborne with Ti post and trying both that the Roox and a Rock Shox suspension post on my Mrs Santa Cruz Juliana convinced me that having more forgiving stays/tyres will get you just the same effect and you need a suspension post for any substantial comfort increase when seated.
That’s all a bit anecdotal but I now use Bel Air saddles rather than the Flite I had and assorted Tompson, I beam and Race Face posts without a problem. The Mrs uses a Thudbuster having gone through Rock Shox and a USE (absolute carp) previously.
I sold the Airborne ages ago and have had numerous “unforgiving” ali frames since including a Cove Stiffee which I was perfectly happy riding the long Meridas on.
