Very nice...that's more or less what I was experimenting with - attached is a rough draft of the pdf export of portions of 3 pages (with the 'locator' maps placed on 1 page for easier viewing -- 1 is the full extent of a strip grid; the other is from a 'pseudo-zoom frame' for lack of a better term.)
Both (or either) can be used, I guess, but what I'll do is pitch the choice to the guys who have to look at them everyday!
Good work.
