100-125 ft behind planer boards. farther out to the side the farther back. shorter as you get closer to the boat. typical spread i use is 125, then 100 then 75 ft on downriggers. Fish in 8-15ft of water this time of year for browns. 15lb test is fine and add a flourocarbon leader last 8 ft. I run sticks(rapalas, smithwicks, etc) and spoons(nk's, michigan stingers, etc.) off the boards. Oswego is always a good bet this time of year. good luck.
