You can catch lots of fish just pulling with one rod. It's easier to watch and less problematic. All you have to do is get deep enough this time of hear. Hot Summer Dog Days. Stay above the Thermocline and you will catch lots of fish. Ad a trailer jig and attach it to the back treble hook on the crank bait. You will catch many more fish this way and they nearly always hit the trailer jig. 1/16 oz. lead head jig with a soft body on it. I use lighter weight line on the jig than on the main line. 10 lb test main line 6lb or 4 lb. test on the trailer jig line. 18" or so behind the cranks. This trick has been around since the 1940s and it was written about many years ago in a Guide Book from Herter's Company. It's still works just as well today as it did 60 years ago. A good quality line counting reel that's calibrated to read perfectly is a great asset. Happy Trolling. I use the Troller Bible and 300 and 700 series crank baits and ten pound test mono. I have a happy trollers plate attached to my motor that slows it down to about 0.5 to 1.0 mph when at idle speed. The lake I fish is 60 ft deep and I catch my fish suspended out over the deepest drop offs. The fish congregate right above the thermocline on the steep drops or just off the drops over the deeper water. Not sure why they stay there at this time of the year. Not sleeping or neutral as I catch a lot of LM bass in this area as well as bluegills. The crappie hang off the shallower drops in like 20 ft of water. The crappie will suspend or hang near the bottom in about 18 ft of water right above the thermocline like the other fish. But they like to have other breaks on the structure such as wood or stickups. Make sure that you have a crank bait lure retriever if you get hung up. They sometimes call them Plug Knockers
