I would not try to turn the first trip into a science project with a short rotation through shoreline cover, weed edges, and the first clean drop away from the bank because good fishing usually gets simpler once one clue starts repeating.
Right now, the inventory connects O'Brien Lake with Black Crappie, Bluegill, Largemouth Bass, Pumpkinseed, and Yellow Perch; so I would pack with weeds, wood, rock, or docks for bass and weeds and easy cover for panfish, and avoid turning a simple trip into a gear-hauling contest.
Going into a first day on O'Brien Lake, I would choose a few spots that look different from one another and give each one a fair chance, and I would not rely on an old screenshot or somebody's memory for current limits.
