Need advice on crankbait type and color.?

hey i have a pond that is a half acre and is located in southern fla. it has bluegill and shiners in it. the biggest largemouth i caught weighed 5 lbs 4 oz and was 23 in long. the water color is a stained green. there are many cattails around the edges. the average depth is 4-10 ft deep. what type/color crankbait should be used for catching big bass. also any other bait reccomendations would be greatly appreciated. thanks.
