If I may continue this "stream of consciousness" thread:
Regarding these "latch" couplers; I'm so used to Kadees I didn't know what to expect from these, much less how they operate. 🤔
As it turns out, they work surprisingly well...they look funny, but they do actually work! 😁
I also have a "318" on it's way, so you all were right about this stuff; it's hard to know when to quit! 😊
