Dual mass flywheel vs the Vibration

I am considering ordering a CTD with the new 6 speed, and wanted to learn what a dual mass flywheel was, as that new part has some rather negative comments here.

So I learn that the design intention of the dual mass flywheel is to reduce noise and vibration...

zfsachs.com
"The engine‘s ignition-induced rotational speed irregularity causes torsional vibration in the vehicle‘s driveline. At a given speed the ignition frequency is equal to the natural frequency of the driveline so that extremely high vibration amplitudes occur that cause transmission rattle and body boom."

This sounds to me like the vibration problem on the 3rd gen CTD that many have had.

So maybe this is a design solution for vibration on the manual, though at a reliability risk.

Do we know who manufactures the unit Dodge is using, and might it be a better one than used by Ford and GM?
