My 2 cents. This year isn’t fishing like typical fall fishing yet and the bite has been tough. If I were going this weekend I would say just cover as much water as possible. 15-25 ft trolling would be where I would focus. You will get a mix of smallmouth, walleye, and northern. Good time to experiment with the lead core. 2mph. the faster you go the less deep your baits run. You will be able to see with the rod If you are hitting bottom. If you are, you are running too deep so reel up 4-5 cranks. Each color (30ft) estimate will get you 5-6 feet down. No need to be kissing bottom. if you are within 3-5 feet you are probably okay. If you are catching 1-2 fish an hour this year, I would say you are keeping up with most!
If you stay 15-20 ft you can get by just long lining deep divers.
