Structure Location?

I am trying to get some good information on where I should put my crappie condo's. I live on Lake Eufaula Oklahoma and I am wanting to structure up a cove of mine. The cove is about 100 yds wide and 1/2 mile long. It is about 15-20 ft in the mouth towards the middle and splits into two necks towards the back 3-5ft of water with buck brush on both sides. The cove has tapering slopes to it not sharp drop offs!! I was thinking of some stake-beds, bundles of willow trees, and brush piles of elm and sycamores. I am just not sure what structure to put where, any information would helpful from you pro's. This area of the lake is an awesome crappie fishery!!:)
