Do plugs dive at all. Last year I ran a DW plug off the ball because I thought they dove a little, so I didn't want them to dive into the ball line. I usually seperate my stackers by 15- 20 ' And the top rods are run out of rod holders pointed out over the water at a 45 angle and the bottoms are turned inside the riggers. I just started doing this last year and managed a few with out any tangles but I am sure they will becoming. Thanks Steve
