First of all, its been a strange spring, lots of good fish or not much happening at all. They don't have to be in constant contact with the bottom but if your color choices are right, you can usually use the ww as a search bait to find the pattern. (Unless your beck or babler who already know the pattern always.) Table rock bass love crawdads!! With the shad kill lately I think that the patterns are hard to nail down. Your probably not doing anything wrong, but these bass can be really picky... Good luck and don't give up
