In dirty water vibration, rattle or anything that makes a noise or disturbance should be the main factor. Second should be a larger profile and third should be color. Darker colors are usually the best because the bass actually see them better, but lighter, brighter colors work as well. Here in NW Louisiana even some of the more natural looking colors work very well. The main thing you should do is fish something that makes lots of noise or gives off lots of vibration. How fast or slow you work it, well let the bass decide. I usually don't get bit unless I'm quickly retrieving or burning it back. I fish a chatterbait most, if not all the time and I fish it really fast with a quick pumping action upwards. No matter how dirty the water was a bass usually finds it, if there's one anywhere near where I'm fishing and hammers it. Usually setting the hook themselves. Most productive colors for me in dirty water are breaking bream, green pumpkin, black/blue and junebug/junebug red. ?
