It really depends what time of the year it is, but a easy clean 6 rod set is; two riggers, two divers, and two long lines. This was our 6 rod summer spread. Last year in the West Mi Fishing League, we where limited to 6 rods. When we set up before light we would use 2 riggers and 4 divers. As it got later in the morning, we would pull one set of divers, and put out two long lines (32# copper lines on boards). As it got later yet we some times would even pull the riggers and add 2 more long lines. Riggers with glow spoons are very productive predawn, but cores, and coppers still shine during the mid day. Divers produce all day. My 9 rod spread would be: 2- riggers, 4- divers, and 3 long lines. If you only have 2 divers, than go with: 2-riggers, 2-divers, and 4 long lines. What you use for the long lines depends on the water temp.
