I fished the Military Bass Tournament on Clarks Hill in 2011, and you ain't lying about it being a big lake and hard to figure out, but once you find them hold on tight. Those spotted bass may not be as big as some of the largemouth on Harris, but fun as hell to catch, especially like you said on a top water bait like a Zara Spook. If anyone else here ever gets the chance to fish it, make sure you go in the spring, and upgrade your hooks before going, and carry extra hooks and split ring pliers, because it doesn't matter what kind of hooks you have on, if you can find those spots schooling and you start catching, those hooks will need to be changed by the end of the day.
