Are Fly fisherman better marketers?

I'm looking to support the claim that Fly Fisherman are more
sophisticated marketers.

Next week I lead a session at the American Marketing Marketing
Association meeting that is built on the premise that Fly Fisherman
are some of the most experienced marketers when it comes to
segmentation... of fish. They consider demographic data (e.g.,
ethnicity, size, age, water conditions, etc) and behavioral, (what
they're biting, what is hatching, what has worked in the past, etc.).

Does anyone have any experience or insight as to whether or not the
prowess in segmenting trout benefits them in their efforts to acquire
and retain customers in the office?

Looking forward to your thoughts.
