I have been running south south west dropping lines at 62 feet trolling to 65 and trolling back to the contour line at 62. picking up fish on the turns.
i have been running a 4 rod spread 2 dipsys, 2 10 color lead core.
dipsy run at 220 setting 3
i believe the down rigger guys are in the 50 foot ball park.
deep spoons 40 to 50 feet have been black and purple, wallmart, black and green, and a spoon that has black yellow purple.
shallow spoons 30 to 40 feet have been jerry lee (orange/white stripe), caramel dolphin, nascar.
this has produced some nice fish for me this year i hope it helps.
good luck.
