When I'm on a lake that has bass I am usually targeting or at least planning on them showing up. What I have learned is more often than not they will mix into other schools like perch, bluegills, crappie with most times not scaring off the smaller fish or they are roaming not far off. Once in a while you might find a school of small LM and that is what you catch. I have never been able to get bit on larger baits like jigging raps or rattle baits, it is more often a small tungsten, 1/16th or smaller jigging spoon, or plain hook with a crappie minnow. They are not near as aggressive in the winter. Tough part is getting a hook set into the hard part of the mouth and keeping them from spitting the hook, don't give them any slack. I have only caught LM never SM and never WB
