KITCHEN LAYOUT.....still almost final

The layout has been discussed ad nauseum, and tweaked, edited, changed, and the still near final layout is below. The last piece of the puzzle is the prep sink- YES or NO, and if so where????

As a reference, here is the 3D version, quite similar to the above, but not as updated.

And finally, this is an ALTERNATE layout, that might be worth trying, but we still have the hurdle of getting used to a sink in the island.
