I also would agree, williams whitefish, white jig and minnow, meegs.
However I find some colours do work better than others, like blue and silver never had much luck with chartreuse for lakers. Another method that always works is the spreader, always worth setting up.
One time i decided to use a giant gold williams whitefish (10 inch)and start ripping it up and down off the bottom to see if i could attract anything to my minnow setup on a another rod a couple of feet away, after a few minutes i see a big red flash on my sonar and feel a huge weight on the williams and began reeling ... well whatever it was i lost it (probably dull hooks) but it felt like the biggest fish i ever set into while ice fishing, that was several years ago up in the Temagami region, so I believe the big flashy spoons do get the lakers attention.
