I agree with 4 salt. I used to guide in very clear water up north. You could often see several kings scattered around a in a hole. Dropping the plugs in at the top and working them down through the hole, the fish would get pushed back until they were in the tail out and then either hit the plug or make a run around it back up into the hole. So driving the fish back by fishing the entire hole was part of the plan, although most of the hook-ups came near the tailout. We used 3 rods with the plugs all out the same distance, which seemed to work best at forcing the fish back.
