I'm in the middle of reading KVD's book right now, and throughout the whole thing he says to not fall into the trap of taking too much stock in the tribal knowledge (for lack of a better term). He says that although some conditions can influence the fish, they can still be caught, and it deals more with angler attitude/mind set vs the conditions. He mentioned that as a pro angler, their schedule is set, and they can't choose what the weather will be when they have to fish, yet they still go out and find 'em. If anyone knows, he would.
