Gus,
The problem seems to be that the two trucks sort of fight each other as the 44 tonner moves down the track. Picture two MU’ed locomotives rolling down the track they sometimes bounce around a little because of speed differences, dirty track, etc. (unless one is always pulling that other). It doesn’t look too bad on large locomotives, but now think about that happening on a locomotive that’s only 4.5” long. My understanding is that the Decoder will feed both motors equally at the same time, thereby smoothing out their operation. (My above comments are based on DC operation. I have no experience with DCC.)
Overall, all of them run really good at slow speeds which surprised me.
GEC,
Sorry for taking your thread off topic.
Here are the links that I found…

and here is the same locomotive on YouTube running really slow with no jerkiness...It's just too cool.
