David, I'd really consider (it's YOUR project, this is a suggestion, realize!) splitting up the "loop" on deck six. IE, have two of the quadrants on deck six and two of them on deck seven (just for example). You get the benefit of a loop, but there's NO portion of the deck which is ISOLATED.
Just my 2cents...
That is a great idea. The isolated area within the loop was bothering me, and that idea fixes it without loss of functionality.
