If I am in an area I know holds decent bass, before changing baits, or changing location, I will change the technique I am using. With plastics, I may dead stick a bait, snap it off the bottom and then let it fall, walk it along the bottom, jerk it in a frenzy manner and pause occasionally. If that doesn't work, then I may change baits, and go through several techniques with the new bait. Then and only then, I may leave this comfort zone and go to another spot I have faith in. Don't overlook the fact that Bass often want a presentation in just a certain way, and often no two days the same way!
