Help with Live rock placement

[CharAznable]

I need some input on my live rock placement in my tank. My tank is 5' x 2' x 2'. It has two overflow boxes along the back. I am trying to place the live rock in a way that looks nice and has good spots to place coral. The only thing that I am really worried about is dead spots. Currently the rock is layed out in the red areas of this top down diagram of the tank:



The gray boxes are the overflows.

Is there a better way I could arrange the rock to minimize dead spots or is it OK to have them up against the back wall?

Just packing rock in will restict flow in those areas causing food and debris to collect. Leave some open areas fro flow and if needed add some spot flow.

Do you have any suggestions on where I could place the rock considering where the overflows are?
