Hope everybody has been staying dry and had a good fourth. Here is my question with a little background info.

Lakes I fish are mostly black crappie. I catch fish well February till end of June by longlining for the prespawn or single polling structure and shooting docks. Once July hits the boat traffic and temps keep me from fishin as much but when I do get to go I generally have no trouble finding fish but getting them to bite can be tough. Much harder to get bit than other times of the year it seems. My thoughts are these fish are much more inactive and picky for many reasons like water temp, storm fronts, lack of current, direction they face in the water, etc.

Here is the question. When you encounter situations like this, what seems to work best for getting bit? As always thanks for the inputs.
