Idling is not influenced by anything in the emulsion tube stack. I have always ended up using the smallest MJ/AC combo that makes correct AFR at high power and does not go grossly lean anywhere else, but I have not used F11 tubes.
I did almost all of my testing in 3rd gear uphill. When I had found the best setup I did a final run in 4th. Sometimes it went a bit lean at the top and I had to drop a size or two in AC's.
You should do a test run in January to make sure that you are not tending lean.
