Unfortunately, experience often dictates both changing lures and moving. When I am out a LOT, I get a feel for what has been going on, and changing offerings: color, presentation, part of the water column... makes sense if I feel they "should" be there. Other times I'm hunting for stupid fish and just keep moving from spot to spot based on structure, tide and conditions.
Good question, I'm sure the real "pros" will chime in soon
If not, you may want to pose this in the New Jersey forum or even in the current reports thread, as more people seem to keep that bookmarked lately.
