Think of it this way.....fish can see 3 to 4 times greater distance than we can, in water. And their lateral line picks up on all vibrations in their vicinity. Those same vibes that the cranks give off.
And more of a factor - to my way of thinking and experience - is that when there is a chop on the water, the fish bite best, for whatever the reason. In fishing the water clarity you indicate, I'd suggest going with the more flashy, bright colors, such as clown, pink/chart., blue/chart. patterns. And try to target the days when there is a 5 - 10 mph wind. JMO.
