In-line boards with Leadcore. That's been the hottest ticket for our gang this year. Lately, 6 to 89 colors the best at 1.6 to 2.0 MPH over ground. As far as how to use them...... Make sure you have enough backing material (Power Pro 30# or 30# mono) (Braid is best). Get them as far away from the boat as wind and waves give you. The farther, the better. 18# Leadcore is perfect for Lake Erie walleyes and can handle most Steelhead. We don't use Downriggers much for walleye. With the clear water, we believe that Dipsey's are a stealthier option. The key to in-line boards is the "Tattle" flag and its adjustment. You need to make sure the flag spring is sensitive enough to show when a small fish is on the bait. "READ" your boards. Any change in the way they line up ..... assume you have a fish or debris that is causing it. Either way, won't catch fish you want.
Hope that helps.
