Julio, does that Thud Buster seatpost do much for your ride on that Nomad?
If I recall correctly Dan has one too.
I have occasionally used a cheap telescoping seatpost on mine, but usually just use the solid post. I run 57mm wide tires on mine, so already have a somewhat smooth ride. My telescoping seatpost, I think the most movement I have gotten out of it is about 1 cm. I have the spring tension adjusted so that my weight does not depress the spring, but any additional force on it would be enough to depress it.
I do not think there is a thread started on Thudbusters, so if you answer, maybe best to start a new thread.
