Can largemouth see my line? Should I worry about line visibility?

It can see line, but less often than anglers fear — and colour is the wrong thing to worry about. To the side a bass sees sharply but with one eye, so a line is a flat, hair-thin streak among stems and shadows; in front, where its two eyes overlap (only about 30–45°) and it could judge where the line is, the view is focused near and stays soft until the last few centimetres, when it is locked on the bait. Largemouth also lean on vision less than smallmouth. So line colour only matters in very clear, bright water on slow baits. Diameter matters far more, because it changes how the bait moves: thicker line is stiffer and drags more. A drop shot with a 3 in (7.5 cm) minnow on a 10 lb fluorocarbon leader and a 1/0 hook usually swims worse than the same bait on 6 lb and a #1 hook — the fish rejects the wooden action, not the line. Size down for action first, stealth second; in stained water or on fast baits, fish whatever strength the cover demands.
