You may have gotten some good warm and fuzzies from tales of his pre-fishing exploits, but don't assume anything. Until a definite pattern is determined, stick with your strengths and instincts. Maybe your first choice of lures or presentations in similar situations on your home water would actually be a better choice. You may end up teaching your partner a thing or two. It's a funny sport.

Factors such as boat position, speed and casting angles often determine the tactics that will be most efficient or practical at any given time. Don't force something that isn't there.

Never be embarrassed to ask questions.
