I have run Church Walleye boards pulling 30-40-50 Jet Divers and 50 TT with Junior Thundersticks or harnesses with no problems up to 2.3 mph in 3' waves. My program is to run 2 on each side aligned in tandom about 10 feet apart. If anything is picked up you will notice it right away. I run the outside boards out about 100' and the inside ones about 80'-85' so they line up with the boat. How far back you run the divers is decided by the fish, usually 90'-160'. Hope that helps you.
