Lots of tips abound, but lets focus on the little things. As you know walleye/sauger fishing success is in the details. Different changes like cadence, size, speed, seasonal movements, bait patterns, low vs high water conditions and low vs high sky conditions all play a part in how these fish will react.
Coots Lures has some of the most aggressive looking, and sounding, crawler harnesses components you can find. All high quality products, with rattles available. I especially like the rattlin crawler harness.
Gamma Techologies produces a slick fluorcarbon leader product that is excellent for crawlers harnesses. Not the brittle products of yesterday, this leader holds up to the biggest fish in the toughest conditions, especially like zebra mussels on the great lakes.
Hutchie makes one fine jig. The live bait and glitter jigs are my go to presentations when fishing vertically in the Mississippi and Illinois Rivers. He also paints one heckuva of a custom color for your cranks.
Work the back side of reefs when pitching jigs as this is where the aggressive feeders are congregating.
Be sure to run one crank high the in the water column. These fish usually dont show up on the electronics.
Harnesses are very successful once the spawn is over and the water warms up a bit. I tie mine with Gamma Flourcarbon Leader. Super strong and stands up to those nasty zebra mussels on Green Bay. Favoritle colors purple and silver beads.
Very the cadence. Instead of up/down, pop the jig 3x off the bottom and hold for a 3 count. Usually the fish hits on the fall.
Walleyes are samplers and saugers are eaters. Walleyes will sample a bait and spit it out in record time. Sauger slam the bait when they are aggressive.
