90% of the walleye we bring in are landed with the boat moving the same as when we hooked them up.... trolling big boards, this also helps the fish center up between the other lines. However - when I know we've got a trophy coming in, I have been known to neutral up to help that fish come in.... but still bump forward enough to keep the boards and the other lines running right. I'll usually neutral up right as that fish approaches the back of the boat, especially if he is on the prop wash side (whichever engine I'm running....). Once in the net, forward we go again.
