I fished Walleyes with cranks last Spring for the first time. I guess I never thought about it, but I caught a LOT more fish on the lines with Planer Boards, than I did with the "down" rods that just run straight behind the boat. I didn't have electronics, and just set my lines back at different distances, then adjusted to whatever the fish seemed to want. Sometimes they just wanted Fruit Dot Bandits, however I dragged them. I found that, if I took the motor out of gear, let the boat slow down to a stop (I sometimes used reverse to get the stop quicker), then engage the kicker, and shoot up to 2+ mph, I got bit a LOT. Lots of doubles doing this, too. I think it triggers a predator/prey response, but haven't actually asked any Walleyes. lol. But it works.
