Depths/length behind ball for 4 rigger set-up

Hi Gents-



I have a Crestliner Sabre 24' that I run 4 riggers on. I have experienced a lot of tangles between the two center riggers. I thought I knew what I was doing, but have lost faith! When running 4 riggers (one off each side, two off back), how far apart depth wise do you separate them, and how far behind the ball on each? The two riggers off the back are about 5' between the bases, Big Jons with 3 lengths of boom, 12 lb balls. How often are you "crossing lines" and ending up with a mess? Any info on your set-ups with spoons, flashers, etc would be appreciated.



Thanks much



Brian
