I am no expert, and my experience on the water is certainly less than some of you other guys. However, in my experience, that old saying is BS. We hauled in some monster loads of crappie this Spring in an East wind... On many occasions. From what I have experienced, stable weather is much more critical than the direction of the wind. 2 days of reasonably stable weather has been my rule of thumb all year.
Also, I look for the water level to be reasonably stable. If it's dropping or rising fast, I usually have some trouble finding fish. That's just what I have found.
High winds out of any direction may turn on the fish sometimes, but it also makes boat positioning so difficult that I lose a lot of fish because I'm more focused on the trolling motor than on my fishing.
That's my 2 cents.
