Catt is obviously a worm fisherman. Learn to rely on feel, not line movement. Once your brain comprehends the line is moving and you reel the slack in, chances are the fish is either gut hooked or will spit the bait. I rely soly on feel. Even if the worm is on bottom and i have a little slack in the line, I can still FEEL the bump. This is where a good sensitive rod and line come into play.
