Ok, Thomas. Here is are the latest changes as near as I could reproduce them. I included a closeup so you could see the tracks labels. Note that these version only have 3 areas where the tracks wouldn't join.
Also note that the 1st 2 photos have my version of the bottom blue run with straights and curves that deleted the "S" curves. However, if the "S" curves don't bother you, the 3rd photo has them. I don't know what equipment you'll be running or how fast, so I don't know if curves will be a problem or not. In this version you can't add Jan's 5" straights to ease them though without reconfiguring the loops.
I suspect the symmetry in the 3rd photo might appeal to you, but don't overlook what you can do with the small pocket by the switch in the other photos if you add some bushes, etc.
