Reply to "K-Line K-29212 CC-M upgrade (1 CC-M + 4 motors)?"

I wasn't expecting DCDR to have cruise but want to better understand if this extremely lurchy starting behavior is:

1. expected from a non-cruise DCDR in command environment
2. not expected but due to wear of the DCDR itself

I think the answer is #1 but it's been forever since I've run a non-cruise DC locomotive and I don't recall if this is typical behavior or not. I expect a CC-M (properly heatsinked) should eliminate this even when driving all 4 motors?

Here's a video of a start to demonstrate what I mean.
