I used to be a die hard crankbait guy about 3 years ago and got a lot of fish fishing them. Then I fished with one of my customers and all he fished was jigs. Well anyway, to make a long story short, he kicked my butt fishing jigs. He outfished me 2 to one every time and with bigger fish. So I finally took his advice and started to fish jigs. My numbers the first year doubled and the quality of fish also increased. From that time on I rarely throw anything else. My three rods in this order are jig rod, wacky worm and a trap or a husky jerk. The first two always produce fish. Now as far as jig fishing goes, since I fish from a boat, I will say that fishing from shore is harder as you will get more snags, lose more jigs and possibly lose fish as you cannot maneuver around easily. With that being the main problem you will catch fish from shore. Jig fishing like mentioned is a very slow process. I literally had to retrain myself when I started jig fishing, because throwing cranks for so long, my reel speed was way too fast. The key to jig fishing is you have to fish them slow, and I mean slow. Cast the jig out wait about 10 seconds so the jigs hits bottom. Wait for a bass to pick it up, if you feel nothing, raise you rod tip up to 12 o'clock position and drag your jig. Lower rod and wait another 10 seconds, see if you feel any taps or any movement. If you do wait for the fish to swim off with it and then set the hook. Now the best way I learned this method was by casting out and closing my eyes. This may sound stupid, but this forces you to concentrate and feel with your hands (since you cannot see and get distracted), line movement, fish bites if any and weeds. Do this until you finally can feel the line movement through the rod guides with your hands. You will feel pick-ups and line twitch because you are focusing with your mind on what you feel not what you see. Once you get to the point of slowing down and start concentrating better, open your eyes and focus on your line. Now you can watch line movement and still be able to feel the taps as you have conditioned yourself to do this. I guarantee if you do this you will catch more fish. Don't give up as this will take awhile . I say about a month or so to get your mind, hands and eyes in sync with each other. I am not an expert, but I would never go back to throwing cranks all day long. I've gotten too many bigger fish from throwing jigs. I use 10 -12 pound mono, mh 6'6'" rod with a baicasting reel. Nothing fancy.
One last thing, is I only fish finesse jigs. This means 1/8 - 1/4 oz jig max with a trailer. I throw nothing heavier and I mainly fish 10 FOW or less. An 1/8 oz jig with a trailer sinks pretty fast in my opinion, but maybe I finally got used to the slowness of fishing jigs, and I'm glad I did.
