Here's some things I do besides the above:
-Keep your speed up, if your cable isn't at 45 degrees or more, then those lock jawed coho don't seem to bite. Basically, you have to piss them off with a fast moving hoochie in front of them.
-Troll at least 3.25 and sometimes faster, especially if going with the current.
-Lots of turns, usually the rod on the outside of a turn will get bit.
-Smooth water with sun, go a little deeper.
-A formula table from a friend on downrigger cable angle and depth of cannon ball: If at 45 degrees you are fishing 75% of depth on your counter due to the blow back of the ball. 100 feet on counter equals approx 75 feet depth of gear.
-Drop back your gear about 15 feet, any further back causes more of belly in your line.
-When one fish hits, adjust DR to depth of hooked fish and keep that line in the water fishing.
-Don't keep trolling along after you caught a fish, turn around and work the area.
May be cruising this weekend so get out there you guys and get 'em!
