Natural Barrier, Ideas

I posted a thread while back about planting bamboo for a privacy barrier but now I am considering planting a barrier of bamboo and honey locust(the thorned variety). I am thinking about planting a barrier of these plants along the property lines for privacy and perimeter security. The bamboo for a screen and the honey locust for an almost perimeter barrier. I don't know whether to plant them about 5 ft apart and make two rows and zig zag the plants. Anyone done something like this? I have nativeblackberry plants and that doesn't give me the privacy because they don't get tall enough and you can see through them. Honey Locust and bamboo do very well here in TN.
