This is great advice. I always watch my line and I use really sensitive bottom contact rods for worm or jig fishing. For Ned Rigs I use a medium spinning row with fast tip and I really watch the line. Sometimes you won’t feel them hit it per se but your line will move in an unnatural way. For spinner baits, chatterbaits or cranks be patient. Let the fish get the bait before you set but certainly with spinner and chatterbaits a strong hook set is key.
