In spring you will see a lot of people in boat clusters jigging in early spring. We used to do that but the fish are mostly small males. So now we skip straight to trolling with deep down crank baits and that produces much bigger fish. The spoon bite usually picks up in later spring. The small 2 1/4” Michigan stingers are the best. Copper back/UV colors. You can tip them with crawlers as well. So the way we fish is crank baits behind planer boards and we always run two spoons straight out the back behind size 30 and 40 True Trips. They’re like jets but way better, easier. It will dive and if you set the hook it trips a hammer that disengages the dive and you aren’t winding against that heavy current on your retrieval. So we have spoons straight out the back during spring so we know when the spoon bite starts. Usually May or so. And then spinner rig bite kicks up when the water temp comes up late spring/into summer. Good thing about trolling is you can use weights and divers, tadpoles etc. You can run a combination of cranks, spoons, spinner rigs, Erie deeries etc to see what Wally wants and when. But we did away with dipsy and jets years ago. Now it’s true trips and I’ve also integrated tadpole diving weights(1.3oz) as well bc you can run them behind planer boards. Do not run true trips behind a planer board and don’t run crank baits behind true trips. Things tend to go awry. I also replace treble hooks on crank baits and spoons with single wide gap walleye hooks or bait holder hooks if I want to run crawlers. It makes life so much easier getting the fish unhooked, not getting all tangled in the net etc. And the treble hooks get buried in the fish, in their eyes, deep down in their gut and all over. So on a small walleye or other species you intend on releasing, treble hooks just tear them up and they die. So the singles are just as efficient, less of a pain to deal with and better for fish. Hope this was helpful. Good luck out there and be safe.
