I have about a dozen cars I run with them. They look great, and don’t have and slinky effect,?but aren’t ideal for ops. They don’t couple without a pretty good amount of force. The cars I use them on stay together, and they do a great job of that. Because they are smaller, the vertical range is smaller, so your track work needs to be good.?The other downside is that they aren’t compatible with any other coupler (yet). I’d hold out for the N-Possible coupler and see if that’s a good fit for you. I did test those out about a year ago and they operated nicely (no slinky).
