Well if you like how it feels, don't change it! If you feel you're lacking comfort on your bike, maybe you should look for a setback seatpost and a shorter stem :)
I wouldn't change mine to a shorter stem. Stem space is precious and it's at the low end of where I like it. I'd have to use the rails to put the saddle in the same place. It'd look like my Cobbl Goblr suspension post.
That' really interesting, I right a straight thomson. Maybe I should change.
Do you have any more info? http://www.cyclingabout.com/wp-content/uploads/2015/07/Seatpost-Damping.jpg
