Thanks to all for the kind words and encouragement! As a high school mathematics teacher, I always tell my students to plan your work and work your plan! I try to model that motto in what I do, as well. I generally build things 100 times in my head before I actually start the physical labor. It is one way to occupy my mind when my wife does not go with me on afternoon walks with the dog 
!
The track plan is simple - 5 concentric, around-the-room loops on a 13' by 32' layout. The scenery will consist of Lemax/Department 56 buildings and figures, for the most part. I've done the detailed, high-rail scenery on my previous layout and it gets to be overwhelming, so much so that I felt I would never get done! This way, my wife, who likes to help decorate the layout at club events can help on the home layout, too. She has no interest in the high-rail scenery either !
The outer loop is O120, followed by a mix of O120 and O96 for loop 4, a mix of O96 and O81 for loop 3, O81 and O72 for loop 2, and O72 for loop 1. Should be able to run the Lionel Big Boy and Challenger at the same time on the outer 2 loops! I had to move the outer loop because of a clearance issue, but at least I caught it now!
Loops 1 and 2 will be controlled by a ZW-L, and loops 3, 4, and 5 are command only, controlled by two PH180's each.
The cable management - I am just fussy !
