You guys are a fantastic resource! Thanks to all. I guess by your answers this is a common challenge. And as desirable as it seems to upgrade the fleet's decoders to the very same exact model, the reality is that in a few years they will be "old" compared to the offerings available. So to upgrade, and try to stay at the leading edge of technology, seems like a very expensive proposition. I hadn't considered setting all momentum to zero and shall try that but this too has its limitations as the newer more robust features in the TCS decoder probably won't be able to be used to their fullest extent (BEMF). So, it doesn't appear there is a clear path for perfection except to further tap into my children's inheritance and keep the decoder fleet current and/or consistent from loco to loco.
I really appreciate everyone taking time to share your collective wisdom!!!
Thanks
