I was running wiring for the LED lights, so took some pictures of the front deck framing. I used 1 1/2" alum angle (1/8') for cross and verticle supports. The two verticle supports go to a floor cross-rib. Deck is cantilevered about 6", so that is probably why I went for two layers of 5/8' plywood.
The LED lighting is done and will get some pictures tonight.
