Personally I troll with diver rather than a down rigger, a Herring dodger type of flasher and an Apex lure 5.5 inches long and I prefer blue/silver, green/silver or the ever faviorte watermellon color.
Also if you use the Apex rerig the lure using at least 30# and a new barbless hook and swivels.
I troll at 1.5 -2 kts.
