Again, sounds like you’re doing the right thing & learning in the process. Changes in bottom contours, such as the ledges you found are often good places. Humps or channels on the bottom can be good too.
IMO once you find the fish, the next key is finding the correct depth to get your lures. It never hurts to vary your lures or depths some either, as different actions may be what they want. Folks with bigger boats up in the bay often troll up to as many as 12 or 14 rods, with specific rods set for specific depths to cover the water column.
But, depending on how many rods you troll with, some types of lures, such as the Mann’s stretch series can be problematic as they tend to tangle with other lines if you try to run to many rods at once. When I trolled them I usually went with 3 or 4 rods, two up, two down. With other lure types I might run 6 to 8 rods unless I was fishing alone. Then I always limited it to 3.
You should give bucktail jigs, spoons & perhaps some other big lipped lures a try if you have them. Depending on your gear, parachutes can also be very productive, particularly for bigger fish. Of course the problem there can be the weight you also have to deal with, as they can be quite heavy so some pretty stout tackle is necessary. I make most of my own, so I always had a wide range of sizes.
Much of the trolling I did was with lighter stuff, even though I have all the heavy gear too. I simply enjoyed the lighter rods & lures better and preferred casting to trolling. Still, sometimes you simply have to do what’s working.
Back in the Chesapeake, I even trolled or cast such things as ribbontail worms or large curltails on jig heads especially in the rivers, as Stripers love eels & those plastics imitate them quite well. I seldom used a jig heavier than an ounce for trolling with them & I would use much lighter, even down to 1/8 oz. if I was casting them.
Keep trying different things & depths. You’re going to catch smaller fish too, that’s part of the game. Stripers are gluttons, they
