I like the new round knob. I have one original LC remote and the Universal (and a Menards). The pointer-shaped handle is not easily operated with just your thumb. I also find that I'm using both hands to operate the remote.
I'm actually surprised that Lionel didn't use a version of the Cab 1, 1L, 2, Red knob on the LC remotes. Where was the marketing department on that one.....
Also big agreement on adding a center off detente. I've slammed a train or two back and fourth trying to get to "off".
The resistors are a good idea too.
Nice work.
