You two guys need to take some lessons from JR. He is the best at STROllING. That's how you get it past 22 ft. Why wear your arm out casting and casting never getting past 15 feet. Drifting or strolling with the trolling motor staying on the contour that the fish are stacked on; get it down there and keep it down there. You can do the same thing with a spinnerbait.
Once you catch a big one then you can start searching with fan casting around the area. If it doesn't work go back to strolling. This is an excellent technique to locating active fish, then set you boat up to start working on them.
