Dave-
I'm wondering what differences you have noted between a good recreational angler and one of the top pro's who depend on the pay check to feed the family?
I've often wondered if a top pro can vizualize what is underwater at a level that I could never grasp. These conversations of bouncing cranks off deep water stumps on a point or dragging a jig in open water of a ledge that goes from 20 to 24 feet and catching limits as a result to me has always been an amazing thought to me. I honestly don't think I can read my graph well enough to even tell what a stump would look like no less to imaging a ditch beside the stump
As I fish an area repeatedly I stumble on to spots that under certain conditions can hold lots of fish. I have memory for these spots and can find them years later. The pro does not have time for this long learning curve.
