I believe there are many different pre fish strategies, but not pre
fishing at all doesn't compute to me. On waters that you are very
familiar with, and have already done your homework, there would be times
when pre fishing wasn't a big deal. But on unfamliar waters, or very
rough weather conditions, I want to "test" some ideas before the
competion begins.
There are many times that conditions change from pre fish to tourament
day, so nothing is ever locked in. I look at it as a "warm up" not much
different from some other sports...get the feel for the "playing court"
g.
If you are worried about the fish....bass have short memories, and there
are probably plenty of fish left there that you didn't hook g. But not
hooking them is the way to go in my opinion.
