Saw something the other day on tv, guy said fish slower/less aggressive on sunny days because the fish relate more closely to structure/cover. On cloudy days speed up presentation/get aggressive and cover water because the fish roam a little more. This was on a green carp show, but seems like it would apply to crappie too. Anybody noticed patterns like this? I know of one day that seemed to be the case but I have never really altered my techniques enough to tell a difference.
