Salmon and lake trout trolling spoons

I haven't had much luck so far trolling in the adirondacks for lake trout and salmon on the smallest mooslook wobbler spoons, wd dreamweaver , and scorpion Michigan stinger spoons .... I was wondering what works better for everyone else for spoon brands and sizes ?would the bigger size large or junior spoons specificaly for mooslook wobblers work than the smaller size I'm using? Also does the copper or gold blanks do better in the tea stained water than Nickel silver blanks ? I mainly fish lake placid, tupper lake , upper saranac lake, Taylor pond , lake george and raquatte lake
