this is probably what everyone does

but in case there is a newbie looking.. on a lake i am familiar with during spring and summer i go to spots that i know have weeds, rock piles, humps etc. and then drills a number of holes and use my vex to find them. then try different tactics, jigs/plastics to get the active/larger fish.
on a new lake i try and look at the dnr maps, before i go out, for a point, drop off, man made structure, or something else that may hold fish. i will also just start where i think there is weeds, or structure judging from the terrain. then i drill a few holes and start working a few different types of jigs with live bait. usually start with a pin min and spike, and twitch it lightly or give it some short bumps of the rod tip and step it up from there to find the presentation they want. pulling the bait up very slowly, or letting it fall slow always works well
